Making a new lawn takes time. Whether you decide to sow seeds or put them in the grass, the pre-preparation must be done thoroughly. It will be much more difficult to fix things when grass covers the ground. But once this is done, a well-laid lawn lasts a lifetime.
The lawn provides you with an instant lawn and can be laid for a large part of the year. The usual time for laying the lawn is from fall to spring, except when the ground is icy or muddy. Laying your lawn in late spring or summer is risky because it may not 'take' properly in hot weather, and in any case, you will need a lot of water to keep it alive. My advice is to stick with fall.

The lawn is an expensive way to create lawns. A decent lawn costs about the same as a carpet. And it takes a long time to put it up. Check what you are actually buying. Cultivated grass is the best buy for a good quality lawn. Prairie grass is cheaper but is often overgrown with weeds and a work lot may contain some lawns that cannot be used because they have bare patches or uneven thickness. Above all, buy the type of grass that suits the type of grass you need. An extremely expensive lawn is a waste of money if it is to be used for football games outside of the league.
People always think that growing grass from a seed takes too long, as you have to leave it for months while it grows. That's true, but if you choose to sow in the fall, you'll have a perfectly usable lawn in the spring. And you probably wouldn't have wanted to wear it much in winter anyway.
You can also sow in spring, but it will be three months before you have a real lawn, which is a time when you would have wanted to use the garden. If an early spring is your only option, the grass is the best option. You can search for the best Turf Installation in Sydney & Windsor via for online references.
If you choose seed, you can select a variety that is perfect for your situation. You can get grass seeds that are suited to dry or shady locations, or that already have wildflower seeds mixed in. But for family use, choose a sturdy mix that contains one of the modern ornamental ryegrasses like 'Hunter'. They look good and do not send pointy seeds.
