Hi Steveo1, many to and fro discussions on the topic in the past. Its a grey area depending on how you read the rules and prob best kept that way given no one has ever been prosecuted that I know of for hobby high-banker use in NSW. Simple rules.....use on Crown Land or "permission granted" private land, don't flow your sediment directly back into the creek, don't dig holes in banks, leave the area the way you found it and do remove other peoples junk if you find any so we don't get a bad name. If we all stick to these rules there wont be too much pressure to clarify the rules...which will inevitably see the end of hobby highbanking.
