1. Protect the tent floor
A ground tarp stops abrasion from grit and sticks that chew through PVC floors. Size it so water sheds outside the footprint.
2. GSM, grommets and tear strength
Reinforced corners and metal grommets matter when you guy a shelter tarp. Heavier cloth shrugs off branches; lighter cloth suits walk-in camps.
3. Multi-use at Aussie sites
Use the same sheet as a picnic ground cover, gear wrap in the ute, or emergency shade. Bright faces help you find camp at dusk.
4. Care after coastal and red-dirt trips
Rinse salt and dust, dry fully before packing, and store loosely. Folded wet tarps mildew fast in humid summers.

7. FAQs
Ground tarp vs tent footprint?
A ground tarp is a general-purpose sheet you can fold under a tent, swag or gear pile. A cut-to-fit footprint matches one tent model. Many Aussie campers use a poly tarp as a cheap, tough underlay.
What GSM tarp for camping?
Light poly tarps (~100–150 GSM) pack small for day shelters. Heavier 300–600 GSM canvas or PVC suits long stays and windy sites. Clear PVC lets light through for verandah cover.
How should a groundsheet sit under the tent?
Keep the sheet slightly smaller than the tent floor so rain does not pool under the fly. Tuck edges in, clear sticks, and avoid sharp rocks that puncture floors.
Can I use a tarp as a fly or shade?
Yes — ridge-line or A-frame setups are common at festivals and river camps. Use strong guy lines, pad sharp tree bark, and drop the tarp in high winds.
Silver/black vs canvas tarps?
Silver/black poly reflects heat and blocks light — good over cars and wood. Canvas breathes better and is quieter in wind but needs drying to avoid mildew after wet trips.
