Official Fossicking Area + Field Research

No specimen provenance, mine status, field boundary or current access permission is inferred from this label.

Stable context

Yowah is a western Queensland boulder-opal locality noted for ironstone concretions known as Yowah nuts.

Stable context

GIA records Yowah’s first opal mining lease in 1884 and places the town about 10 km south-west of Koroit.

Current official visitor layer · checked 2026-09-11

What the reviewed official sources support now.

Queensland Government identifies Yowah as a fossicking area. The official page says camping is prohibited in the fossicking area and excluded mining claims/former lease areas must not be entered. A current fossicking licence is required. Verify the source page and current road conditions before travel.

Visitor guidance class

Official fossicking area

This describes the source-backed publication scope of this BOU route. It is not a live open/closed status.

Camping

Camping prohibited in fossicking area

Camping rules are stated only where the reviewed official source supports them. A camping permit never replaces a fossicking licence.

Licence + permission

Current licence required; actual land/tenure permission still matters

Where land is not specified fossicking land, current Queensland guidance can require written landholder and mining-tenure permission. Historical mining evidence is never permission.

Road / travel status

Not republished by BOU

BOU does not state a live road, weather or closure condition. Use QLDTraffic and the locality/rules pages immediately before travel.

Before travel: re-check the current fossicking licence, land and mining-tenure permissions, locality-specific camping/access rules, personal safety guidance and QLDTraffic. Conditions and permissions can change after this BOU check date.

Formation connection · BOU005

What this field contributes to the model.

GIA reports that Yowah opal is found mostly in siliceous ironstone concretions, with other forms attached to ironstone or sandstone and multiple concretion-bearing beds. This statement remains scoped to Yowah.
