You are 100% correct here Spotty- both were manufactured by Danfab Engineering in Australia under license from Reverchon.
The G Force at LPM was removed in early 2015 and replaced with the Power Surge.
As for Wonderland's Tasmanian Devil: "The Tasmanian Devil was Built for Australia’s Wonderland in 1985 and was slightly smaller in diameter than the other explorers they built and had the capability to go backwards, for whatever reason Australia’s Wonderland chose to operate it in one direction only. The Tazzie Devil was half trailerized but not completed for travelling on the show circuit."
Here is a bit more info on the Explorer ride ( Thanks to Dave Burton's Amusement Ride Extravaganza site)
"
The explorer was first manufactured by Reverchon Industries of France in 1980. Reverchon, a pioneer in the electric bumper car. Several units were made under license in USA and Australia in the early 1980’s with approximately 30 built worldwide before production ceased by Reverchon around 2001.
The ride consists of a fast undulating rotational movement with 3 ups and downs per revolution ranging from 0.5 to 5 metres (1.6 to 16 ft), with a swinging sensation, both clockwise and counter-clockwise direction. Unlike similar rides the hydraullically driven Explorer does not use a tram guide to lift and lower the cars but instead an ingenious reverse eccentric centre hub.
The large 40-person ride is mounted on one 46ft trailer and can be set up in as little as 4 hours with 3 people.
There are approximately 5 Reverchon units operating in Europe, at least 5 in USA and 3 Explorers in Australia - one at Melbourne’s Luna Park, one immaculate road model renamed Flashdance owned by Chant’s, and an ex-park model under refurbishment. These 3 were built in Australia under license from Reverchon in the 1980’s.
