Australia does not have one lawn-sowing calendar. It has at least six, because a soil thermometer in Darwin and one in Hobart are never telling the same story on the same date. A couch grass sown in Brisbane in August can be up and running before a fescue sown in Ballarat has even started to think about it, and that gap is not marketing, it is basic soil temperature.
This hub is where we match the two variables that actually decide whether grass seed strikes: which state you are in, and which season it is. Warm-season species such as couch, kikuyu, buffalo and zoysia need sustained soil temperatures of roughly 18 to 20C or more before they will germinate reliably. Cool-season species such as fescue, ryegrass and Kentucky bluegrass will get moving from about 10 to 12C. Match the species to the season your state is actually having, not the season on the calendar, and you will get a better strike rate.
We are building this out one quarter at a time. Spring pages for all six states (Victoria, New South Wales, Queensland, South Australia, Tasmania and the Northern Territory) are live now, ahead of the September sowing window. Summer, autumn and winter pages for each state follow as those seasons approach. Western Australia is served separately at wa.mckaysgrassseeds.com.au because of that state's quarantine rules on grass seed imports.
Pick your state below, then pick your season.
| State | Spring | Summer | Autumn | Winter |
|---|---|---|---|---|
| Victoria | Sow this Spring | Summer, coming soon | Autumn, coming soon | Winter, coming soon |
| New South Wales | Sow this Spring | Summer, coming soon | Autumn, coming soon | Winter, coming soon |
| Queensland | Sow this Spring | Summer, coming soon | Autumn, coming soon | Winter, coming soon |
| South Australia | Sow this Spring | Summer, coming soon | Autumn, coming soon | Winter, coming soon |
| Tasmania | Sow this Spring | Summer, coming soon | Autumn, coming soon | Winter, coming soon |
| Northern Territory | Sow this Spring | Summer, coming soon | Autumn, coming soon | Winter, coming soon |
Note: Western Australia is intentionally excluded from this grid and lives on the dedicated wa.mckaysgrassseeds.com.au store, which sells only WA-quarantine-compliant seed.
6 cells live now (all Spring). 18 cells are placeholders for Summer, Autumn and Winter, to be filled in as each season approaches.
