Quick answer
Optus is usually the stronger all-round pick if you want a major carrier and broader confidence beyond the strongest metro zones. Vodafone is often the sharper value play for city-based users, especially while its half-price first-six-month offers are live.
Price and promo structure
Vodafone's current SIM-only page on 18 June 2026 pushed very aggressive first-six-month pricing on 60GB, 200GB and 400GB plans. Optus also used promotions, but its headline discounts generally run over 12 months instead of six months.
That means Vodafone can be the better short-stay or fast-switch option, while Optus can look stronger for shoppers who expect to stay longer than one billing cycle but still want a deal.
Coverage trade-offs
Coverage is where the comparison becomes practical. Optus is usually the safer middle ground for Australians who do not want the cheapest answer if it comes with a weaker footprint. Vodafone can still be excellent in the right metro areas, but it should be checked carefully if you work, travel or live outside major-city strength zones.
Best by user type
Metro users and budget-driven switchers should check Vodafone first. Regional users and broader-coverage shoppers should usually lean Optus if they do not want to pay Telstra prices. Heavy-data users can make a case for either carrier depending on whether they care more about promo value or ongoing price.
Travellers who value simple roaming should also give Vodafone real credit because the current page leans heavily on its $5 roaming proposition.
FAQs
The most common Optus vs Vodafone questions are not about brand image. They are about whether Vodafone is good enough where you live, and whether Optus is worth paying extra for once the promotional period ends.
