Fossicking in National Parks is illegal in QLD.
Fossicking within a defined distance of a bridge or culvert is also illegal. Reference: QLD Fossicking Act 1994
Fines apply and yes equipment can be confiscated (vehicles too I've been told)
Use of highbankers with water supplied by a pump also illegal in QLD according to some (including Mines Dept inspector)
but many disagree on this.
Their (Mines) logic is..you cant use power operated water pumps to assist fossicking...and you are still fossicking (including processing) dirt until you find the fossicikng material ( gold or gems).
You can sell ringside seats to the fight and disagreements that follow a post such as this.
My advice is for people to read the QLD Fossicking Act and satisfy themselves. No-one has been prosecuted to best of my knowledge.
Highbankers and rockers using a hand operated water pump seem to be quite OK.
Can someone now start supplying popcorn....
