Yes we'd definitely need to research. When I say Sandgate I actually mean Brighton, Deagon (shorncliffe would be wishful thinking). Looking at property you can get a decent 3 bedder at 400k on double the size plot that we have here in Sydney. And there yo have Sandgate station. I used to commute by bus and train to Brisbane from Redcliffe for work o I have some idea about the commute. Or else were thinking Petrie as well.
We're going up or Easter so we have a bit of time but definitely would not move up without researching it thoroughly. DH and I are renowned planners
