Below we explore some of the best grasses for this area, their strengths and weaknesses, care tips and preventive measures against pests and diseases. 

Recommended grass varieties 

1. Buffalo Grass (Stenotaphrum secundatum) 

   - Strengths: Tolerates heat and is drought-resistant, making it an ideal choice for the warmer months. It has a dense root system that helps outcompete weeds.

2. Kikuyu Grass (Pennisetum clandestinum)

   - Suppliers: Turf Australia, Queensland Turf Producers Association. 

3. Zoysia Grass (Zoysia japonica) 

   - Strengths: Known for its shade tolerance and resilience against drought, Zoysia is great for lawns that experience partial sunlight.

Basic grass care products 

To maintain your grass effectively, consider the following care products: 

- Fertilisers: Choose a slow-release fertiliser suitable for your grass type. Look for nitrogen-rich blends to promote healthy growth.

2. Mowing: Regular mowing helps maintain grass health. Different grass types will have varying recommended mowing heights, so adjust accordingly. 

3. Aeration: Aerate your lawn in early spring to allow water and nutrients to penetrate the roots better.

While winters in Southeast Queensland are milder compared to other regions, grass care still requires attention: 

- Adjust Mowing: Mow less frequently as the grass growth slows.  

- Water Sparingly: Grass typically requires less water in cooler months, but still stays attentive to dry spells.
