If you're a thrifty NBN user you're probably jumping between plans according to which provider offers the better deal on any given month. Plenty don't lock you into a contract, so if you see NBN 250 or NBN 1000 going cheap, and want to enjoy high speeds at low costs it while it lasts, there's nothing stopping you except time.
If you've got the time and want to spend the effort, Telstra is currently offering AU$40 off per month both its Superfast NBN 250 and Ultrafast NBN 1000 plans. Telstra tends to be a bit pricier than the competition, but AU$100 a month for NBN 250 is great—it's usually AU$140 a month with Telstra, and this offer throws in a three-month subscription to Binge as well.
Meanwhile, if you're after Ultrafast NBN 1000, that's AU$140 per month for the first six months, before rising to AU$180. You can quit out before that price rises, but do note that with these plans you'll need to pay AU$216 for the Telstra smart modem. In other words, the total minimum cost for NBN 250 is AU$316, and for NBN 1000 it's AU$356.
But if you do stick around for at least the first six months, that being the period with the cheaper price, you'll be saving AU$240.
