Thanks JD. I'm aware of this report and am digesting it as a view into Australia's macro outlook for this sector, appreciate your effort.
The briefing paper
@hoogs4 linked to however refers to PEP11 though-out, including analysis which was presented to NSW parliament, which I find interesting, as PEP11 in 2021 is still a political play, just as it was in 2010. Of particular note is this section on the "community view" of Pep11 circa 2010-11. We have seen this all before...
Briefing Paper No 01 / 2011
Offshore petroleum exploration and mining
by Daniel Montoya3.4.1 Community viewsPEP 11 has been the subject of substantial media coverage,
most of which has been published in the regional paper adjacent to the location of PEP 11 – the Newcastle Herald. While the Newcastle Herald has allocated space to the Advent Energy position, including claims that offshore gas drilling in PEP 11 could create "tens of thousands of jobs and generate billions of tax dollars"47, the majority of the coverage has identified community concerns regarding offshore drilling.A coalition of community and environment groups, which included some local government councillors, opposed the offshore drilling for two reasons: they held "serious concerns about the potential for environmental damage to the coast and marine life"; and believed that governments must begin the transition to a "clean, renewable energy economy and away from the fossil-fuel economy."
48 Further concerns cited in media coverage include the lack of consultation conducted by Advent Energy (according to community groups
49 and several Commonwealth MPs
50), and disappointment with the NSW Government's decision to not release the entire Environment Plan to the general public.
