Preston is a rural locality in the Whitsunday Region, Queensland, Australia.

[4] The main road route through the locality is Conway Road which enters the locality from the north-west (Mount Julian / Mount Marlow), passes through the town of Bonavista, and then exits to the south-east (Conway / Palm Grove).

The lower-lying land is mostly in the west of the locality and is used for growing sugarcane.

There is a cane tramway to transport the harvested sugarcane to the local sugar mill.

[4] The town of Bonavista was originally called Conway, which was derived from Cape Conway, which was named on 3 June 1770 by Lieutenant James Cook, commander of HMS Endeavour, after British Secretary of State for the Southern Department, Henry Seymour Conway.
