Hi Rubiks
Just been up to Brisbane for a week. Drove up taking 2 days (allow 24 hours if you have kids). Fuel for us in a Holden Astra cost about $217 to get back to Melbourne and still had half a tank! Didnt calculate going up but assume we spent approx the same.
We too think Melbourne is okay but the winter weather isnt up to much. Must say though the beaches and sea on Mornington are fab compared to Caloundra and Gold Coast as they are very rough with waves and the little ones have to be watched. There may be calmer waters but we didnt come across them as we didnt have much time. We were in shorts and t shirts and swimming in the water! Came back here and its bloody nithering!!
Loved Brisbane city and the South along pacific Motorway Shailer park area to be precise. Loved Coomera and the GC hinterland but need accessibility hence the motorway location. Only 30 mins from City or GC. Not tourist season but i would hate to be in the GC when it was as sooooo busy.
Brisbane city has a very holiday feel to it with bars in the middle of Queen Street Mall. You can catch the River Cat and use your train tickets to cover all the transport.
Streets Beach fantastic plus FREE as are all the swimming pools we came across.
Anyway apart from the Cane Toads all is good there as far as i can see. Just got to sell our house and get up there.
Sorry to all that love Melbourne but you are welcome to it

i much prefer milder weather all year round and yes even the 3 or 4 months of absolute unbearable torturous humidity. I came to Oz for a reason and that was to feel i was in Oz but in Melbourne i feel i may as well be back in Yorkshire freezing me .... off!!!
Get yourselves up there and see for yourselves i would be suprised if you didnt like it
