Greg is regularly engaged to act and appear in significant Corporations Act matters and in complex general commercial disputes, including contractual disputes.

Greg came to the Bar in 1995 following 5 years as a commercial solicitor with Freehills (now Herbert Smith Freehills) where his work included capital raisings, mergers and acquisitions and advising listed public companies on matters such as corporate governance, share plans and general meetings.

At the Bar, Greg has acted in a broad range of commercial matters. These have included matters in the areas of takeovers and reconstructions, shareholder disputes (including oppression proceedings), partnership disputes, investor class actions (being the Westpoint class action and the Fincorp class action), corporate insolvency, managed investment schemes (where he acted for the liquidators of Gunns Plantations Limited), professional negligence, building and construction, trade practices, aviation, copy right and Aged Care.

While Greg has an extensive corporate and, commercial practice, his predominant areas of practice are in the fields of the Corporations Act (including takeovers and reconstructions through a scheme of arrangement), corporate relationship disputes such as oppression proceedings and partnership disputes, contractual claims arising out from a share sale agreement or sale of business, complex commercial disputes requiring detailed review and analysis of extensive documentary evidence, the duties of fiduciaries such as directors, partners and trustees and corporate advisory work in relation to commercial transactions. Greg has also acted for a number of rural law clients (click here for details).

Greg's corporate and company law practice includes acting for publicly listed companies, unlisted public companies and proprietary companies.

Examples of work undertaken by Greg in these corporate and commercial fields are set out below.

Takeovers and reconstructions (through a scheme or schemes of arrangement under the Corporations Act)

Greg has acted in 36 schemes of arrangement including schemes to effect takeovers, mergers, demergers and internal reconstructions. These have included schemes of substantial transaction value such as the 2019 $4.4b takeover by Brookfield of all of the shares in Healthscope Limited (in which Greg acted and appeared as lead counsel for ASIC as intervener at the first court hearing), the $1.9b takeover of Sirtex Medical Limited in 2018 by CDH Genetech Limited and China Grand Pharmaceutical and Healthcare Holdings Limited, the $3.8b merger in 2016 of M2 Group Limited with Vocus Communications Limited, the demerger in 2011 of Treasury Wine Estates from the Foster's Group, the subsequent $10.5b takeover of Foster's in 2011 by SABMiller and the $1.95b takeover in 2010 of Healthscope.

For many years Greg has acted and appeared alone in substantial and complex schemes of arrangement. Greg has also led junior barristers in schemes of arrangement. Greg has acted and appeared in a broad range of schemes of arrangement encompassing takeover (or change of control) schemes, demerger schemes, merger schemes, top-hatting restructure schemes, destapling restructure schemes involving share schemes and a trust scheme and internal reconstruction schemes involving orders under section 413 of the Corporations Act. Greg's experience in this field of the law extends beyond the issues and challenges that commonly arise in schemes and includes navigating schemes through the court process in the context of bidding contests, shareholder activism and acting for a bidder where the target company was the subject of a class action.

Greg has acted for target companies, bidders (including private equity) and for ASIC. In the majority of the schemes in which Greg has acted, he has represented the scheme or target company (being the plaintiff in the proceeding and the company responsible for obtaining the required court orders for dispatching the scheme documentation and for having the scheme of arrangement approved). Greg however has also on many occasions acted for bidders (inclduing overseas bidders) in takeover schemes of arrangement, where such bidders have incuded private equity as well as commercial trading companies. As such, Greg has an understanding of the issues required to be addressed by bidders including regulatoty approvals, funding and corporate finance/financial assistance matters. Greg, as noted above, has also acted for ASIC and as such has an undertanding of schemes of arrangement from the regulator's perspective.

Recent schemes of arrangement (and trust acquisition proposals) in which Greg has acted include the 2021 takeover of Asaleo Care Limited by Essity Holding Company Australia Pty Ltd (in which Greg acted for Essity), the 2021 acquisition proposal by Roc Partners for the units in the Vitalharvest Freehold Trust (a listed managed investment scheme) in which Greg acted for Roc Partners, the 2021 acquisition proposal by NorthWest Healthcare Australia RE Limited for the units in the Australian Unity Healthcare Property Trust (an unlisted managed investment scheme) in which Greg acted for NorthWest and where the acquisition proposal was opposed by the responsible entity, the 2020 takeover of OptiComm Ltd by Uniti Group Limited (in which Greg acted for Uniti Group and which involved two competing proposals by Aware Super Pty Ltd), the 2020 takeover of Village Roadshow Limited by BGH Capital (private equity) (in which Greg acted for Village Roadshow Corporation Pty Ltd - the largest shareholder in Village Roadshow Limited and which involved shareholder activism by an Amercian based investment fund) and the 2020 takeover of DWS Limited by HCL Australia Services Pty Ltd (in which Greg acted for HCL Australia Services Pty Ltd following the first court hearing).

Other recent schemes in which Greg has acted include the 2019 takeover by Brookfield of all of the shares in Healthscope Limited (in which he acted and appeared for ASIC at the first court hearing), the 2019 takeover by Kokusai Pulp & Paper Co. , Ltd ("KPP") of all of the shares in Spicers Limited (in which he acted for KPP), the 2019 takeover by Adamantem Capital for all of the shares in Legend Corporation Limited (in which he acted for Legend Corporation Limited), the 2019 takeover by Wesfarmers Lithium Pty Ltd (a wholly owned subsidiary of Wesfarmers Limited) of all of the shares in Kidman Resources Limited (in which he acted for Kidman Resources Limited), the 2019 takeover by Shell Energy Australia Pty Ltd ("Shell") of all of the shares in ERM Power Limited (in which he acted for Shell), the 2019 takeover by Quadrant Private Equity for all of the shares in QMS Media Limited (in which he acted for QMS Media Limited and which was approved by the Court in February 2020), the 2018 takeover of Sirtex Medical Limited (in which he acted for the bidders) , the 2017 proposed takeover of SMS Management & Technology Limited by DWS Limited (which did not proceed by reason of a third party offer) (in which he acted for SMS), the 2016 takeover of Patties Foods Limited by an entity owned by funds managed or advised by Pacific Equity Partners Pty Limited (which invovled cash/scrip consideration) (in which he acted for Patties Foods), the 2016 takeover of Unity Mining Ltd by Diversified Minerals Pty Ltd (in which he acted for the bidders), the merger in 2016 of M2/Vocus referred to above (in which he acted for M2), the 2015 internal restructure of AusNet Services (which involved destapling the relevant securities and an associated trust scheme), the 2014 takeover of Oakton Limited by Dimension Data Australia Pty Limited (in which he acted for Oakton) and the 2014 internal reconstruction/amalgamation of the Little Real Estate Group. Greg was also retained (2015) in relation to the demerger of Clydedale Bank from the NAB.

In some recent schemes of arrangement in which Greg either acted alone (or was leading a junior) he has helped to shape or clarify the law in certain important areas in this field of the law.

By way of example, in the 2019 Brookfield takeover of Healthscope Limited, Greg appeared for ASIC at the first court hearing on 16 April 2019 to make submissions on "class" composition in respect of the proposed scheme of arrangement. Justice Beach's judgment in respect of that hearing (handed down on 18 April 2019) contains a detailed discussion on the class composition question. See Re Healthscope Limited [2019] FCA 542

Further, in the 2019 Wesfarmers takeover of Kidman Resources Limited, Greg's submissions on behalf of Kidman Resources Limited at the first court hearing on 30 July 2019 included submissions on the "director benefit/director recommendation to shareholders issue". Justice O'Callaghan's judgment in respect of that hearing (handed down on 7 August 2019) contains a discussion on that issue. See Re Kidman Resources Limited [2019] FCA 1226

Greg's work in the field of schemes of arrangement has included addressing the issue of shareholder activism, including

  • the very recent Village Roadshow Limtied scheme in which there was shareholder activism by an American based investment fund.
  • the 2018 Sirtex scheme (in which Greg acted for the bidders) in which Sirtex Ltd was a respondent in a Federal Court investor class action proceeding at the time the scheme transaction commenced through to the approval and implementation of the scheme (which proceeding was still on foot post implementation of the scheme).
  • the 2011 Cellestis scheme of arrangement (in which Greg acted for Cellestis Ltd) in which there was a shareholder action group

Greg's work in this field extends beyond the court process and includes pre-announcement review of transaction documents, advice on discrete transactional issues, advice and input regarding the structure and content of the scheme booklet, advice regarding recourse to the Takeovers Panel, the consideration of and proposed response to issues raised by ASIC, matters relating to foreign law deed poll advice, matters relating to overseas regulatory approval and drafting involvement (post scheme implementation) in respect of financial assistance documents relataing to loans advanced by lenders to fund a takeover transaction.

Greg has also co-lectured on the subject of "Schemes of Arrangement" (as a senior fellow) in the Melbourne Masters Program (University of Melbourne Law School) and has given seminars to law firms who practice in this area.

Greg is available to act in schemes of arrangement both in Victoria and interstate. Greg has appeared interstate in schemes of arragement having appeared for the bidders in the Federal Court in Sydney In the Sirtex Medical Limited scheme of arrangment. Greg has also appeared in the NSW Supreme Court on behalf of Shell Energy Australia Pty Ltd as the proposed acquirer in the ERM Power Limited proposed scheme of arrangement.
