The ABC’s Antony Green has a piece on electoral boundaries and redistributions, it seems those living on the Canberra/Fraser border could be in from some adjustment:
The ACT’s boundaries were gazetted in December 2005, so a redistribution fell due at the end of 2012. As the House of Representatives was due to expire within twelve months of that date, the ACT redistribution has been deferred. It will begin as soon as the 2013 election is over.
The ACT’s boundary adjustments are likely to be minor. The northern ACT seat of Fraser currently has around 7,000 more electors than the southern seat of Canberra, so the likely change is a minor adjustment to the boundary between the two seats.
