Southern Queensland encompasses some of the most challenging and diverse grazing landscapes in the state — from the low-rainfall mulga country of the Channel Country to the fertile, higher-rainfall Darling Downs and subtropical coastal ranges.
South Queensland — semi-arid rangelands
The semi-arid south is characterised by low, highly variable rainfall (300–500 mm), Mitchell grass and mulga grass communities, and a strong legume component in the native pasture in good condition years. Key challenges:
- Drought frequency — severe droughts are expected every 10–15 years; contingency planning is essential
- Mulga dieback — overgrazing removes protective ground cover and exposes mulga to heat stress and borers
- Slow recovery — degraded rangelands in this zone may take 5–10 years to return to productive condition
Carrying capacities in this zone are typically very low (1 AE per 20–50 ha or more) and must be planned around long-term average rainfall, not good years.
South East Queensland — improved systems
The Darling Downs, South East Queensland ranges, and coastal lowlands support more intensive beef systems, including:
- Improved subtropical pastures — kikuyu, setaria, Rhodes grass, panic grass
- Fodder crops — sorghum, millet, oats, and forage brassicas integrated with grazing systems
- Irrigated pastures on the Darling Downs — higher-value enterprises with intensive management requirements
- Tick management — SEQ is tick country; management programs are critical for herd health and movement permissions
Weed pressure in SEQ
African lovegrass, lantana, and Coolatai grass are significant invasive species in the SEQ ranges and tablelands. Early detection and rapid response programs are the most cost-effective management approach.
