Tableland Travels

What could be more fun than a bush walk through rainforest on a track that features an abandoned railway bridge, a freshwater swimming hole, a suspension bridge, and the chance to spot a Platypus? The Peterson Creek walking track at Yungaburra has all of these things. There’s also abundant bird life and butterflies too!

The Peterson Creek track takes about 1-2 hours and is considered a Grade 2 walk, meaning no bushwalking experience is required, though there are some steep sections (and, let’s face it, not everyone is going to like the suspension bridge). We chose to start the circuit at the roundabout in front of St Patrick’s Church. After a short walk along Mulgrave Road, we turned left onto a grassy corridor – where the railway line once ran.

The Tolga to Atherton section of the Cairns to Ravenshoe railway line was opened in 1903 and a branch line from Tolga to Yungaburra opened in 1910. The rail bridge over Peterson Creek was completed in 1958 when part of the branch line was rerouted to make way for the Tinaroo Dam. In fact, three steel bridges were constructed for this line across Peterson Creek, Barron River and Mazlin Creek. The bridge over Peterson Creek spans 78 metres; its steel girders sit 28 metres above the creek bed, supported by concrete piers. Its use was very short-lived, as the line closed in 1964.

The track then begins to climb slightly, and follows the path of the creek along an elevated ridge. After negotiating a steep pinch down stone steps and crossing a footbridge over a ravine, we were rewarded with a surprising vista when the bush track opened on to a sunny little glade next to a swimming hole. Frawley’s Pool was named after a local schoolteacher named Mick Frawley, who reportedly taught many children how to swim there. A shady little stream running beside the grassed picnic area completed the delightful scene.

Further along, a short diversion down a sidetrack takes you to Williams Weir, and the site of a water wheel turbine, which used to supply power to the village of Yungaburra. A point of interest for lovers of old machinery, is an old Fitz-Burnham turbine, on the site of an old pump house, which was used to pump water from the creek up to the village.

Perhaps the most fun part of the walk is traversing Lloyd’s Suspension Bridge, which spans 30 metres across Peterson Creek. Planned by Yungaburra Landcare Group, it was engineered by Robert Colefax, designed and built by John Nott and privately funded by Lloyd Abell. A sign warns that no more than 10 people at a time should be on the bridge. I think I prefer one person at a time, as the timber platform sways quite significantly under your feet. Understandably so – it’s a suspension bridge after all. I suspect visiting children love its wobbliness.

On the other side of the bridge the track hugs the creek line, and its here that you are very likely to spot a Platypus – if you’re quiet, and you stop for long enough. We did see one, but it darted through the murky water so fast, I only got a (very) blurry photo. Plenty of Saw-shelled Turtles were posing for photos though. The trail meanders a little further on, skirting the boundary fence of adjoining farmland, then you walk underneath the road bridge (on the Gillies Highway) and then up to the Platypus Viewing Platform, which is basically the end of the track. We’ve never actually seen a Platypus from this viewing platform, perhaps because there is so much noise from the traffic on the road right beside it.

The Peterson Creek walk is also known as an area where the Lumholtz Tree Kangaroo can be seen, but we lucked out on this occasion. The Yungaburra Landcare Group have spent decades rehabilitating the Peterson Creek area, revegetating endangered forest plants and maintaining the walking track, and the sheer beauty of the place is testament to their efforts.

Mount Isa – Excursions in the Spinifex

Generally speaking, the first thing that anyone notices about Mount Isa, whether flying in or driving in, is the Mount Isa Mine. It dominates the view from all directions. For almost 100 years, Mount Isa’s vast mineral wealth — its copper, lead, silver and zinc — is what the city has been best known for. But the Mount Isa region (the traditional lands of the Kalkadoon peoples for over 40,000 years) is also rich for another reason — its beautiful, ancient landscape.

Apart from the mine, which, let’s face it, cannot be unseen — one of the first things I noticed when I landed in Mount Isa for the first time (on a research trip for a history book I’m writing) was a profusion of wildflowers that lined the roadside from the airport to the city. The clumps of Mulla Mulla (Ptilotus exaltatus) — a native of arid and semi-arid areas of Australia — with its conical-shaped, pinkish/mauve-coloured flowers, proved to be a prelude to the natural attractions of the area.

For a start, there is abundant bird life here. One afternoon I drove out to Lake Moondarra, about 17km from Mount Isa, to do some exploring. This lake was created in 1957 when a dam was built on the Leichhardt River to provide the inhabitants of Mount Isa with a reliable water supply. I spent a very pleasant couple of hours out here, wandering around in the scrub out the back of the dam spillway, carefully trying to avoid scratching my legs too much on the spinifex grass. I saw a pair of galahs picking at the rough, rocky ground; a Red-winged parrot; a Cloncurry Ringneck parrot; a few crested pigeons; and several yellow-throated miners.

On Sunday afternoon, I was fortunate to have friends (who are locals) drive me out to a place they called “the granites” to watch the sun set. It’s an abandoned granite mine, technically part of the Sybella granite batholith* — and geologically, it’s estimated to be around 1,660 million years old. That’s an impressive timescale. Situated on private property, the site is about 20km outside of Mount Isa, and accessible by 4WD vehicle only. After passing through an unmarked gate, a dirt track soon winds past a field of monolithic lumps of granite, mined but later abandoned, all laying about like some kind of collapsed Stonehenge in outback Queensland.

A little farther on, a massive outcrop of pink granite rises up from the track, scattered with rust-coloured spherical boulders, often stacked impossibly precariously on top of each other. Soon, the granite outcrop flattens out, allowing a panoramic view of the entire plain below it. It’s a spectacular scene that stretches far off to the horizon, where the sun drops rapidly behind the ranges. As the last of the light faded, the rocks behind us began to change colours, assuming a luminous, ethereal quality that was spellbinding. It’s an afternoon that I won’t soon forget.

On the flight out to Mount Isa, I was re-reading the book Travels in North Queensland, by the writer Jean Devanny. She is best remembered as an author of fiction, but it is her non-fiction “travel books” (of which Travels in North Queensland is one) that interest me the most. Devanny (writing in the mid-20th century) thought that the town of Mount Isa itself was “vital and captivating” and “intriguing and alive”, and the scenery leading out to Mount Isa beautiful, but when it came to Mount Isa’s natural attributes, she was apparently less than impressed.

The road and railway line out to Mt Isa, which mostly ran parallel, traversed narrow levels between ironstone ridges stained puce, purple, red, blue, cinnamon and rust. Broken rocks disclosed the yellow heart of crumbled hills. The earth itself was honey brown. On all sides rose well-timbered tors, flat-topped, peaked or rounded. All the cattle, even in patches of spinifex, were fat.

But Mt Isa itself, sprawled over a lumpy arid basin encircled by ironstone hills [was] for the most part barren of vegetation and minus the aforesaid colouring.

Perhaps if Devanny had been able to see Mount Isa from the air, as I had done when I flew in, she might not have thought it to be so devoid of colour? The cinnamon and rust coloured ridges of the Selwyn Range and the honey-brown earth were certainly there — in my eyes at any rate. Perhaps we really only see what we want to see?

I’ll admit I was lucky enough to have been shown around all the scenic parts of Mount Isa by my friends. I wish Devanny had seen those granite spheres at sunset.
