Parker advises energy, resource and infrastructure clients on laws related to hazardous materials, air and water quality, contaminated land, climate change and renewable energy. He also specialises in regulatory matters and M&A transactions involving development, land use and water approvals.

Earlier this year, Jones Day poached another long-serving Allens partner, Stephen McComish, to lead the global firm’s new Perth office, which opened in April. McComish had been a partner in Allens’ dispute practice for almost a decade.

Parker and McComish are among several partners who have departed Allens this year.

On 5 November, Lawyers Weekly exclusively revealed that Allens had lost industrial relations and employment law partner Jamie Wells to King & Wood Mallesons.

Within a week, infrastructure and construction law specialist Ren Niemann, who started his legal career at Allens and had been a partner there for seven years, defected to McCullough Robertson.

Other senior exits have included competition and regulatory specialist Jo Daniels, who left the firm in April to launch Baker & McKenzie’s new office in Brisbane; and M&A partner Alex Ding, who defected to Lander & Rogers in July.
