flight path or power lines I would say neither keep looking !

been someone with older winkies they DONT use the land ! how much bigger are we talking, is it acres or just like 800sqm 550 sqm is tiny as far as land goes, but you will be close to work / city, if you are planing on saying there in Tazy forever and this would be you forever house, you should check out schools in the area, see what the towns are like, you might find the one which is better than the other... ( I know small towns can be very hard to break into when your not a local unless your born and bred there so keep this in mind too )

Also check out what the PT would be like witht he house which is out of town, as when you have older children they will want to be dropped off and picked up a fare wack, look at if there are things for the kids too do in the smaller town ie out of school sports, places for them to get a part time job when the time come for it... just loads of stuff that isnt on your mind right now but you might regret if you stay forever and didnt think about it now...

I know in Tazy 20min drive is HUGE and everyone will think you crazy for driving that far... plus if you choose to go back to work once the kids are at school it would mean you driving in to...

Ok I know I havent been much help, the decion is yours and DH's to make, I hope some of my ramberling has made sence and given you something to think about...
