The two electorates that top and tail the Illawarra look likely to become even safer Liberal Party seats after the redistribution of electoral boundaries.
Proposed changes to the NSW electoral boundaries were announced in June and were officially gazetted by the government last week.
The changes mean Kiama MP Gareth Ward and Heathcote MP Lee Evans look certain to hold on to their seats at the 2015 state election, which is when the new boundaries take effect.
Mr Ward's seat - which he holds with a margin of 7.5 per cent - will shift south, taking in Nowra's Liberal-voting tracts and his old Shoalhaven City Council stomping ground.
Mr Evans' northern electorate will move away from the Illawarra to take in the conservative suburbs of Bangor and Woronora in the Sutherland Shire.
Meanwhile, in the central Illawarra seats, Ryan Park's Keira electorate will move slightly north to gain about 10,000 voters from Bulli, Thirroul, Austinmer and Coledale - adding more Greens and Coalition voters.
This change will make the Keira electorate one to watch at the next election, with Mr Park now holding the traditionally Labor seat with a margin of 3.9 per cent.
Changes in Wollongong and Shellharbour would be minimal, with relatively small shifts proposed to even out voter numbers.
In Wollongong, Noreen Hay will gain Towradgi and parts of Mount St Thomas but lose Kembla Grange, Brownsville and the northern side of Kanahooka Road.
In Shellharbour, Anna Watson will represent additional parts of Marshall Mount and Dapto, as well as households in Shell Cove.
Despite potential political implications of the draft redistribution of boundaries, the changes have nothing to do with voting intentions.
The law requires a redistribution after two elections have been conducted using the same electoral boundaries, and decisions about any changes are made by three independent electoral district commissioners.
In 2015, each electorate must have between 47,493 and 58,047 voters.
NSW electoral boundaries last changed in 2004 and were in place for 2007 and 2011 NSW elections.
