Its not a bad drive Spotty, I was posted to Brisbane for two years, so did the trip quite a few times. I also rode my BMW K100RT to Canungra via Brisbane in 1991 and loved it, even with a hangover most mornings after a big night's drinking at the end of each 500 mile day.
I left Brisbane for the return trip via Sydney still drunk from the previous night (engagement party) so didn't start to feel the effects until I was across the border in NSW, and as much as I'd hoped to make Sydney that night I only got as far as Newcastle before I had to stop for the night.
I pulled into the first motel with a vacancy sign, and bugger me, the manager was from Melbourne, his wife was away and he was bored, so invited me to drink free booze with him all night. Once more, I hit the road feeling like I'd gone 10 rounds with Cassius Clay......
