While lambs in the eastern states suffered large price falls this week, the trend in WA has been much more varied, according to Meat and Livestock Australia.
The WA trade lamb indicator gained 5¢/kg from last week, to 294¢/kg (carcase weight).
But MLA says this is a 13¢/kg increase on the same time last year.
The WA heavy lamb indicator followed the trend set in the eastern states to fall 18¢/kg.
However, the WA heavy lamb indicator is also down on the same time last year, to the tune of 32¢.
In contrast, all other states have gained.
WA mutton experienced the greatest jump, increasing 47pc on last year, to 119¢/kg this week.
This mixed price trend can be partly attributed to the mainly smaller yardings at the two markets reported by MLA's National Livestock Reporting Service.
Katanning declined 37pc for sheep and 5pc for lambs, while Midland's sheep yarding fell 21pc and lambs remained unchanged on last week.
