As much as I'd love to go to Hawaii, $2500 not going too go far. Shoot up to Cairns enjoy esplanade go do Sky Rail and Kuranda Train (day package), stay at Green Island a couple of nights or so, while the wife is lazing around hire a sup (checked profile), flat water and close small reef break right tide, snorkel around and do the lovey dovey things with wife. Then head up to Port Douglas, enjoy the vib, do a half day trip to Mossman Gorge and a day on the outer reef from Port, every one's happy

Oh and do it around October, wind's generally dropped off and water's nice and clear, less chance of rain, days nice and warm but not humid

I don't think Severne will mind me posting this...
