The Coalition is set to retain the Brisbane seat of Bonner comfortably, in a sign Labor is failing to make inroads in the key Queensland marginals it needs to win to be in with a chance on July 2.

While the seat has changed hands at every election since it was created in 2004, new ReachTel polling commissioned by Fairfax Media shows the Liberal National Party's Ross Vasta on track to win easily.

The poll shows Mr Vasta leading Labor's Laura Fraser Hardy by 56 per cent to 44 per cent on a two-party preferred basis, which would be an improvement of his 54/46 result at the 2013.
