Places like Walga Rock are so isolated and visitors are so few and far between it's not feasible to have the physical presence of an attendant at the rock. The protection of such a valuable site is enormously important and relies on the the sensitivity of visitors to this amazing place.
Driplines have been installed above the paintings to protect them from water running down the rock, trees have been planted across the face of the cave to shield them from the sun and bushes growing close are kept cleared in case of fire, but the main thing is for visitors to look but never to touch the surface of the paintings and to be sure to close the gate behind them as they leave.
No-one would want to see visitors barred from the rock, hopefully the awe the place inspires will ensure those who come respect these measures.
Gold fills mens' dreams. Individual prospectors and small companies have never left these goldfields but now the price of gold is strong there are bigger players back on the scene.
Hill 51 at Mount Magnet, 80km south of Cue is the biggest operation in these northern goldfields. Mines are dangerous places and tourists aren't allowed on site, but there is a lookout point from where you can get a good idea of the operation.
Look out along the road and you will see the signs of other workings - this land is rich with gold reefs and there are many small operations all around.
5km south of Cue lies Day Dawn - once a thriving settlement with thousands of men working the mine and the diggings. Now all that remains are a few sad ruins and this substantial building, the Great Fingal Mine Office. The office may be locked and shuttered, but nearby a mine has opened and gold is being mined again at Day Dawn, as it is all over the region.
There's still plenty of gold in the ground around Cue, but the people have gone. The price of gold plummetted with the Great Depression and in 1933 the last mine closed.
The windows of the Gothic timber and iron Masonic Hall are shuttered and broken, but the solid golden limestone buildings are still there. Tourists come in winter and spring when the desert becomes a sea of flowers; the rest of the year, the town is nearly deserted - not quite a ghost town.
The supply of gold seemed inexaustible, new mines opened all around and the town prospered. The people of Cue were proud of their wealth and proud of their town. Photographs in the small museum in the Municipal Chambers show a thriving community with smartly dressed men and women enjoying their prosperity at weddings and balls, race meetings and picnics. The Gentlemen's Club and the Masonic Lodge built grand lodges for their members and the town band played in the Bandstand on Saturday nights. It seemed as if the town could only go from strength to strength.
