More Information
Turf is a big investment both finacially and in terms of time and effort, so a little research before you buy will be well worth the trouble. Species readily available in Qld for backyard lawns include:
Digitaria didactyla (Queensland Blue Couch)
Cynodon dactylon (Green Couch)
Stenotaphrum secundatum (Buffalo or St. Augustine)
Dactyloctenium australe (Sweet Smother or Durban Grass)
Besides the basic species, there are many named selections and hybrids of turf grasses on the market. Some are protected by Plants Breeders Rights (PBR). Some may be more suitable for professionally maintained sports fields than domestic lawns. Others may be relatively new on the market, so yet to prove themselves under local conditions.
Some considerations in making your selection may be drought hardiness, heat and cold tolerance, shade tolerance, salt tolerance, invasiness (of garden beds etc), fineness and softness of leaf, resistance to foot traffic, growth rate. Depending on the particular situation, some of these criteria may be more important than others.
When consulting with your turf supplier, explain your needs to help them make an appropriate recommendation for your yard.

New solution to the shaded turf problem
A giant moveable tray allows the playing surface at University of Phoenix Stadium (host to the 2008 Super Bowl) to be grown outside and wheeled in for games. Turf cultivation inside stadiums presents special challenges, as this post at The Human Flower Project blog explains: 106 Million Players: Super Turf '08.
Aussie natives may deliver more sustainable turf
Australian native grass species will be considered in a breeding program to select turf grasses that look good with less water and fertiliser. Read more at the University of Queensland website: Turf grass, just add (less) water

Zoysia
The mossy-looking ground cover sometimes seen for sale in garden centres is Zoysia matrella var. pacifica but you will probably see it sold as Zoysia tenuifolia. Zoysias grown for lawns on a larger scale include selected cutivars and hybrids of various Zoysia species. Bear in mind that the exact properties of cultivars referred to in the following links may vary from Zoysia turf varieties currently available in Australia. Performance will, of course, also be affected by local environment.

Artificial Grass
Developments in artifical grass are making it an increasingly attractive alternative for many, given water shortages in addition to the general work associated with growing and maintaining an attractive lawn. It also makes a grass-like surface possible on concrete, rooftops, indoors etc, where a grass lawn whoul be impractical or impossible.
