2004 enviro app was approved, page-3

Harry, I received an email from MEC Corporal Dev Officer Toby Foster which in part said

"A previous Referral under the EPBC Act to the Commonwealth Department of
Environment, Heritage, Water and the Arts (DEWHA) was withdrawn due to the nature of changes required in that document to keep it current. Following advice from our environmental consultants, Advent has deemed it unnecessary to Re-refer our actions to DEWHA for their consideration. Notwithstanding, Advent will comply with the EPBC Act, and all other applicable Acts and regulations, uring its activities within PEP11."

The bit that says 'to keep it currrent" - could that mean that they already have approval (as you say approval has already been given to drill Biggus in PEP11 on 15/11/2004 - and they will be using this approval and just updating it with a new drill site?
