No negative impacts should result from opening up a new part of Australia's eastern seaboard to gas exploration, NSW MPs have been told.
Advent Energy, which holds most of the controversial exploration permit PEP-11 off Sydney and Newcastle, sought to allay fears on Monday about its proposed activities more than 20km offshore.
It's trying to convince NSW MPs to halt proposed legislation that would ban offshore gas activity in state waters and hamper any industry trying to set up in deeper, federally controlled seas.
