aaNet is waiving its regular $129 fee for anyone connecting or churning to them before the end of January. Their ADSL2+ plans are particularly good value, eg 20GB monthly, up OR down, (not combined) for $29.90 if bundled with phone line. They've recently extended their service in regional areas (like Hobart…)

On a related note, for anyone considering switching, it appears that the iinet deal has been extended until 31 Jan.
