AgForce president John Cotter said daylight saving may work well in southern temperate climates, but Queensland's hotter summers mean it would be a backward step for a State the size of Queensland.

"Queensland is a vast state and as the Premier has rightly said the city of Cairns is as far west as Charleville which has implications in terms of what time of "the working day" the sun rises and sets – regardless of whether we have daylight saving or not," Mr Cotter said.

"While some people make jokes about cows not milking or the curtains fading, there is a more serious side to this debate.

"It is about people and the fact that daylight saving is strongly opposed by the majority of the regions in Queensland."

Mr Cotter said the Premier's decisive stand on this issue and to govern for all Queenslanders makes a lot of sense.

"Any suggestion of a split time zone to accommodate daylight saving in the south-east is completely impractical and would increase the perceived divide between the south-east corner and the rest of Queensland."
