My hubby wants to move from Tweed to Gladstone for work. Need Advice!

My husband wants to move myself and our 3 kids 9,5 & 19 months to Gladstone so he can be a truck driver there and make apparently $2000 a week in a company, he was offered a job recently as he was up there with current employer. BUT my 2 eldest kids have behavioural/learning disorders and need 3 monthly reviews of meds etc. I have one of the best paediatricians on the Gold Coast that has looked after them for years and I don't believe I will find one better up there, and our GP is excellent also. They go to a private Christian school here and teachers are fantastic and understand my children. My son goes to daycare most days of the week as I study from home, one of my kids and I see a psychologist also and I really want to have good advice from ppl there about all this. Where I live now we have big shopping centres, big w all that sort of stuff, take away places everywhere, beach, great schools, doctors, paediatrics, hospitals, and housing prices are not that high. I'm afraid moving there has limited things unless u drive, petrol is very pricey and not much to do, is this true?
