Area approximating everything north of the Flinders Highway from Camooweal in the west to Townsville on the east.
In this zone, which includes cattle tick, Three-Day sickness and buffalo fly zones coupled with heat, humidity and monsoonal rainfall, there are greater challenges for Angus bulls, however, they can still be used effectively. Careful management including acclimatization, parasite treatments, seasonal mating and reduced handling during warmer weather is strongly recommended. Almost entirely used in cross-breeding programs and stabilized composites.
Area approximating everything east of the cattle tick line from the QLD/NSW border up to Torrens Creek and south of the Flinders Highway between Torrens Creek and Townsville.
Typically, more humid and increasing heat load the further north with the presence of cattle tick, buffalo fly and Three-Day sickness. Encompasses a large portion of the Brigalow Belt, some Desert Uplands country, Central Queensland Coastal Country and South East Queensland.
Angus bulls and females can perform well when managed appropriately through allowances with nutrition and breeder herd management. Cross breeding is also common, especially along the coastal and adjacent areas and more northern areas in the Capricornia, Central Highlands regions.
Area approximating west of the tick line up to approximately Torrens Creek, heading in a westerly to north westerly direction following the Flinders Highway to Camooweal. Encompasses approximately 95% of the Cattle Tick Exclusion Zone.
Characterised through warm to hot summers and cooler winter conditions with low to moderate humidity. A range of country types encompassing; Mulga Lands, Channel Country, some Brigalow Belt, Mitchell Grass Downs and North West Highlands country.
Angus bulls and females under reasonable management regimes exhibit productivity and longevity. Cross breeding programs is also common, particularly with bos indicus type cattle.
