Is the recent supply squeeze an indication of a flock rebuild?

31 Jul 2026

Key points

Most sheep and lamb indicators hit record highs over the last month.

Mutton supply has shown a much tighter contraction compared to lamb in 2026.

The heavy contraction in sheep slaughter and recent Sheep Producer Intentions Survey results point to signs of a flock rebuild.

Sheep and lamb supplies have tightened significantly across Australia in recent months, pushing many market indicators to record highs. A summary of these recent records is outlined below.

Trade Lamb Indicator - 1,244¢/kg carcase weight (cwt) on the week ending 12 August 2026

Light Lamb Indicator - 1,184¢/kg cwt on the week ending 12 August

Mutton Indicator - 916¢/kg cwt on the week ending 12 August 2026

Merino Lamb Indicator - 1,152¢/kg cwt on the week ending 12 August 2026

Restocker Lamb Indicator - 1,235¢/kg cwt on the week ending 28 June 2026

Online Lamb Indicator - 253¢/head on the week ending 7 August 2026.

Recently, signs of demand cooling off have seen indicators begin to drop over the last two to three weeks. All indicators have declined over the last month, with drops ranging between 2% for the Heavy Lamb Indicator and 10% for the Light Lamb Indicator.

As per the typical seasonal trend, winter maintenance periods for some major sheep and lamb processors began from mid to late June. However, this year’s winter has seen a noticeable decline in slaughter compared to previous years.

National slaughter data confirms just how tight supply has become this winter. In June, 1.52 million lambs were processed nationally – the lowest June lamb slaughter since 2020, down 11% on June 2025.

Mutton has had an even more significant drop, with sheep slaughter falling 58% year-on-year from 633,679 head in June 2025 to just 267,738 head in June 2026. This is the lowest June sheep slaughter since June 2020, with July numbers still to be finalised but expected to be similar.

The trend runs deeper than one soft month. Year-to-date (January–June) lamb slaughter sits at 10.36 million head, down 14% on the same period last year but just 1% below the five-year average, which is 10.46 million for 2021–2026.

Sheep slaughter presents a much stronger market signal. After three years of exceptionally high slaughter rates, year-to-date sheep processing is down 41%, a sharper decline than anticipated. This suggests that, in addition to a reduced flock, producers are retaining breeding ewes rather than sending them to slaughter, supported by improved pasture conditions following a better-than-expected first half of 2026. This aligns with findings from the latest Sheep Producer Intentions Survey and helps explain the record highs recently seen in the Mutton Indicator.

With sheep numbers falling faster than lambs in terms of availability to processors across almost every state, the mutton and cull-ewe pipeline has tightened the most. The sharper decline in sheep availability points to producers' intention to rebuild the flock as a driver of the current supply shortage, underpinning strong competition among processors for available stock.
