Settle the legal question on the exact blockThere are eleven declared fossicking areas in Tasmania and no licence is needed inside their boundaries. Everywhere else, MRT states that fossicking without a prospecting licence is illegal. The historic goldfields at Beaconsfield, Mathinna, Lefroy and Corinna are not fossicking areas. Start on the map rather than on a place name: open Detector Maps over the spot you have in mind and read the land status and tenure layers, so you know whether you would be standing inside a declared area, on live tenement or on freehold. MRT is the source for the licence rule itself. Sort this out before you build a trip around a place name.
Carry the tenement, reserve and boundary layers with youExploration licences, mining leases, conservation areas, national parks and the Tasmanian Wilderness World Heritage Area all cut across old goldfield country, and several fossicking areas exclude neighbouring reserves and private blocks. The declared fossicking area boundaries are proclaimed by MRT, so treat its published boundaries and area rules as the legal word on where the line sits. The rest is map work you do yourself: put the land status, reserve and live tenement layers up in Detector Maps, zoom in on the block you actually intend to walk, and download that area so the layers and your GPS position keep working once you are out of signal.
Read the conditions for the specific area, then put them on the mapHand fossicking only, no power-operated or mechanised equipment and no explosives, a 10 kg limit per person per 48 hours, no fossicking in caves or underground workings, no vehicles off formed tracks, no undermining of creek and river banks, and diggings restored before you leave. Metal detectors are not permitted in the declared fossicking areas. Individual areas add their own rules, such as the 200 m exclusion either side of the Hastings Caves Road centreline at Coal Hill. MRT is where you confirm the conditions that apply to your area. Anything spatial belongs on your map before you drive: measure that 200 m offset in Detector Maps and mark the edge, so the limit is something you can see in the field instead of something you are guessing at.
Ring the land manager before you commitMost of these areas sit on state forest or Crown land. Sustainable Timber Tasmania asks visitors to contact the regional office to find out what activities are occurring, whether heavy vehicles are using the same roads, and where gates are locked. Parks and Wildlife handles the reserve areas, including the current Tea Tree Point closure at the western end of the Penguin area. Those calls are the official word on access and closures, and the answers are worth keeping. Drop a pin in Detector Maps on each locked gate, haul road and closed section as you are told about it, so the route you plan matches the ground you will actually be allowed to drive.
Study the historic workings from homeRaces, sluiced faces, dumps, dredge tailings and shaft lines show up clearly on LiDAR hillshade and on old plans, and they tell you both where the ground was worked and where the hazards are. This is the part Detector Maps is built for. Run the bare-earth hillshade to pull those features out from under scrub, cross-check them against the mapped historic workings and the historic topographic and georeferenced map overlays, and save a pin on anything worth a look and anything worth staying well clear of. An hour on the map beats a day of wandering, and on the north-east and west coast fields it is also a safety exercise.
Download offline maps and tell someoneParks and Wildlife advises carrying a map because mobile phone range cannot be relied upon, and coverage is patchy across the west coast, the deeper north-east forests and remote parts of Flinders Island. Download the area in Detector Maps before you leave, so your maps, your saved spots and your GPS blue dot all keep working with no signal. Then tell a reliable person your route and expected return time, record your intentions in log books where they are provided, and carry a personal locator beacon for remote trips.
