You enter the tube one-on-one with the trainer while the other skydivers sit and watch to see how well you've remembered the instructions about turning, dipping, spinning and rising. Too much fun. The wind grows in force and before you know it you're suspended in the air. Your cheeks and lips wobble like a happy dog out a car window and the whole experience is surreal.
After a minute or so you fly back to the door, get high-fived by your fellow skydivers and hope they've decided you weren't too unco for a first-timer. A woman in our group was in her mid-70s and seeing her overcome some very visible nerves was awesome.
Once you've done a few flights it's helmets off, goggles removed, ear-buds out and, away from the thunderous wind jets, you can compare your flying yarns. I'd love to do it again.
From skydiving to "skywalking", the next calorie-burning stop on the GC was in the lush Hinterland, less than an hour from the beach. Cooler in temperature, mountainous and drenched in greens, this is a side of the Gold Coast far removed from the brashness of Surfers. The Tamborine Forest Skywalk (rainforestskywalk.com.au) takes you on 1.5km of forest trails, highlighted by 300m of steel bridges that weave high into the canopy.
The walk is done in about 45 minutes, criss-crosses 12ha of forest and encompasses a significant breeding ground for rare butterflies. If you're passionate about rainforests and the benefits of eco-tourism, Tamborine Rainforest should be a Gold Coast must and seeing this part of Queensland via an elevated "skywalk" is one of the easiest ways to experience it.
Continuing the altitudinal theme, it was a short drive to a place that modestly bills itself as "the most extreme adventure attraction on the Gold Coast". Treetop Challenge, as part of Thunderbird Park, is something of a rugged theme park in the forest. Rope courses and rock climbing are among the activities but it's no question that the star attractions are the zip lines of the "Canyon Flyer".
With groin-bulge enhancing harnesses tightly secured, the Canyon Flyer at Treetops has you more than 60m above the ground and travelling at speeds of up to 70km/h. Zipping backwards and forwards across the mightily scenic Cedar Creek Canyon, we were a varied bunch that included tourists from India and China. The Chinese couple smiled enthusiastically after every instruction, though the repeated meeting of buttocks and platform suggested the words "jump forward" may not have been entirely understood.
As is often the case with a zip-lining operation (and they're springing up everywhere - this was my third time after forests in Rotorua and northern Thailand), the guides were young and energetic and gave every indication they really liked their job.
The same was true for my first ever time on a jet-ski. The following morning I was back on the coast and snaking my way through the mangrove forests and white-sand beaches around South Stradbroke Island. I'd wrongly consigned jet-skis as an obnoxious relic of tacky places like Pattaya in the 90s, but things changed as soon as I saw the big grins of Dave Grohl and his Foo Fighters band-mates on the photo wall at Jet Ski Safaris.
The old adage: if it's good enough for Dave (who'd visited a couple of years ago), it's good enough for me. And it turns out - shock horror! - that speeding over calm waters in 30C heat while exploring subtropical islands is actually a lot of fun. Who knew! The obnoxious factor is greatly reduced given Jet Ski Safaris keep their guests and skis on a tight, polite leash within the marina before letting you loose well away from anybody else.
The waterways of the Gold Coast are genuinely beautiful and that was the reason I gave for being the slowest in the group. I'm sticking by the story! Admittedly, it's fair to say that if it had been high school PE then I wouldn't have impressed anyone. "I can't believe you're not unco!" said no-one when I was the last to park up my jet-ski. But how attractive had those islands and waterways been? Luckily I was going slow enough to see them.
