The route and what to expect
Highland Lakes Road is signed A5 and links the Midland Highway in the south with the Bass Highway near Deloraine in the north. The road climbs from the southern Midlands through Bothwell and Miena, skirts the shores of yingina / Great Lake and descends through the Great Western Tiers toward Deloraine. Much of the route follows open plateau and moorland rather than forested corridors, so views are exposed and weather changes are often obvious and fast.
Services, supplies and staging
Services thin quickly once you pass Bothwell. Plan fuel stops and carry extra fuel or a top-up if you have any doubt about remaining distance to the next service centre. Pack food, drinking water and warm, waterproof clothing. If you intend to stop at Miena or use a northern service centre, Deloraine provides conventional town services. Take these factors into account when planning day runs or overnight stays.
Weather, road conditions and timing
The Central Plateau is high country and weather can be changeable throughout the year. Frost, snow, strong winds and low cloud can occur with cool-weather systems and may affect road surface and visibility. Check the forecast before you leave and consult up-to-date road-condition advice. Where possible, avoid night driving: the combination of isolation, livestock and native animals on the road increases risk after dark.
Driving hazards and vehicle suitability
Parts of the A5 are steep and winding, especially on the descent from the plateau through the Great Western Tiers. Expect narrow sections, wildlife and livestock on the carriageway. Watch for ice in cold spells and for vehicles crossing the centre line on blind corners. The main sealed A5 is suitable for two-wheel-drive vehicles when open and in good conditions, but a four-wheel-drive vehicle is required to access the interior tracks beyond Lake Augusta into the conservation area. If you plan to use any unsealed tracks in the reserve, check local access notices and track condition information before setting out.
Reserves, hydro infrastructure and access rules
The A5 forms the eastern boundary of the Central Plateau Conservation Area and provides access to lake shores and lookouts. Use formed lookout points and designated lake access areas. Do not enter operational canals, dams or fisheries infrastructure. Yingina / Great Lake is managed for multiple uses including hydro generation and recreational fishing; lake levels are managed and can vary. Check Hydro Tasmania for current lake-level information if boating or planning shore access.
Fishing, protected waters and biosecurity
Yingina / Great Lake is a managed trout fishery and supports both recreational angling and significant conservation values. Certain shoreline zones are reserved for artificial lures and flies only. There are minimum sizes and bag limits that apply to trout in parts of the lake. All waters flowing into Yingina / Great Lake and a defined radius below inflows are closed to fishing to protect native species. Do not transfer live fish, fish products, plants or water between inland waters. Check, clean and dry boats, trailers, waders and gear before moving between waters and before you enter Tasmania.
Camping, fires and other site conditions
Much of the Central Plateau Conservation Area is a fuel stove only zone where open fires are prohibited. If you plan to camp, carry an appropriate fuel stove and follow the reserve's fire restrictions. Camping inside the conservation area requires that you bring quality cold-weather equipment suitable for exposed and changeable conditions. Some internal tracks and gates may be seasonally closed for public safety. Contact the Great Western Tiers Field Centre for current access conditions if you will use interior routes.
Practical timing and seasonal notes
Autumn and spring commonly see stock movements and grazing herds on the southern stretch of highway around The Steppes. Expect to share the road with sheep and cattle during these periods. A boom gate on some internal roads may be closed in winter months for safety. Given variable operations and seasonal closures across hydro and reserve infrastructure, check weather, road and field-centre notices in the days before travel.
Safety checks before you go
Before setting out, confirm current road conditions and any reserve alerts. Carry spare fuel, warm clothing and food, and make a plan that avoids remote night travel where possible. If you intend to fish or boat, verify the local regulations and lake access arrangements and follow biosecurity steps to avoid transferring freshwater pests. For interior tracks beyond Lake Augusta, ensure you have a suitable high-clearance 4WD and check with the Great Western Tiers Field Centre about seasonal closures or track advisories.
