Where to live when working near Brisbane?

My family and I will be moving to Australia in the next two months and have still not decided upon an area. My husband has just had an interview for a job in Brisbane Technology Park, ( Eight Mile Plains). Like all Brits, we want a large house with a pool which is close to beach and has excellent schools and community vibe. We don't know anyone in Brisbane so would need to be able to settle in quickly. We don't mind not being in Brisbane but commute to tech park needs to be no more than 45mins. Our kids are 9 & 2 so schools, parks and safety are crucial. We have a budget of around $500pw and we want 4 beds, space and pool - please give me some indication of the areas we could afford.
