But 5G isn't getting cheaper just yet.
Both Telstra-powered providers have just a single 5G mobile plan, sitting at the top of their range. ALDI is the cheaper of the pair, charging $55 for a 30-day recharge with 50GB. Woolworths Mobile is a little more expensive at $59 per month for 60GB, but Woolworths Mobile subscribers also get 10% off their Woolies grocery shop once per month.
In both cases, these plans are capped to speeds of 250Mbps. That's pretty fast, but only a quarter of the real-world speeds we've seen on the Telstra 5G network.
Both providers also represent better data-for-dollar than Telstra's entry-level Upfront plan, where you'll pay $58 per month for 40GB. This plan's speeds are also capped to 250Mbps.
Here is how the trio of plans compare:
Boost Mobile is the only other Telstra MVNO to offer a 5G plan. The plan is billed at $70 per recharge and includes 65GB of data. You do however get 35GB of bonus data on your first three recharges, bringing it to a total of 130GB during your first three months.
While it's early days for 5G on smaller Telstra providers, the pricing across MVNOs fits with the trend we've seen with the Optus network. 5G is currently a premium proposition, and smaller providers don't have the ability to undercut their parent networks in a meaningful way. This is quite different to 4G-only plans, where MVNOs can offer much better deals.
