142 Days leaves you so much that you could do. Australia and the general Asia/Pacific region has lots to offer
What interests you and your son?
Do you want something active (eg Bungee Jumping, Kayaking, Mountain Bike Riding, Mountain Claiming) or do you want something sedate (a nice retreat with activities to keep the little tacker amused) or a combination of both.
Seeing as you're bringing your son with you, whatever your interests, make sure you visit the
War Memorial in Canberra, the
Cadbury Factory in Claremont (or ... I believe ... Christchurch, NZ), and take a trip out to Ularu or The Olgas. Head to Longreach to the
Stockmans Hall of Fame and the
Qantas Founders Museum.
There's heaps to do. Qld is very Tourism Patriotic, and in fact we offer 3 shows on local TV each week with things to do in and around Qld. Check out
The Great Southeast's website for info.
Tell us a bit more about your plans, you, and your son, your budget, and we're sure to give you lots of info.
