Telstra, Optus, and Vodafone have announced price hikes on several mobile plans in Australia, with changes expected to take effect across different dates in April and May 2026. The price increases will vary, with mid-tier or prepaid options typically rising by around $5 per month. Higher data allowances will often accompany the change, while some plans may see smaller or larger increases depending on the specific postpaid option. The new prices will impact both postpaid customers, with the exact date of implementation differing depending on the carrier. The price hikes are part of a broader effort to adjust service plans and offerings.
