Fifty-two lenders are now offering at least one variable rate below 6%, up from a handful six months ago, as smaller players use aggressive pricing to pull share from the majors. The lowest advertised variable rate sits at 5.69% with no loan-to-value ratio restriction, more than half a percentage point below the owner-occupier average of 6.25%.
The question for borrowers: is a sharp discount today worth the refinancing friction if that rate reverts to standard pricing in 12 months?
Who’s cutting and who’s staying put
Non-bank lenders, regional banks and credit unions are leading the sub-6% wave. Several mid-tier players trimmed rates by 0.11% to 0.17% in the past week alone, targeting new borrowers with principal-and-interest deals at high loan-to-value ratios.
The big four banks have held official pricing steady. That doesn’t mean their rates are fixed, retention teams are negotiating case-by-case discounts for customers threatening to refinance, often matching or coming close to advertised challenger rates without the public rate cut.
Investor loans carry a higher floor: the average investor variable rate is 6.48%, with the lowest advertised investor rate at 5.94%. The gap reflects lender appetite for owner-occupier volume over investment lending in a softening rental yield environment.
The mechanics behind the discount
Sub-6% pricing is part new-customer acquisition cost, part funding arbitrage. Smaller lenders with lower legacy cost bases can price more aggressively than the majors, and some are willing to accept thinner margins for 18-24 months to build loan books they can later securitise or portfolio-manage at scale.
The risk: these rates are often honeymoon or introductory structures that revert to standard variable pricing after 12 months. A borrower refinancing into a 5.69% deal today could face a reversion to 6.5% or higher once the intro period expires, wiping out the savings unless they refinance again.
Fixed rates are also moving. Four lenders cut 37 fixed-rate products by an average of 0.17% in the same week, bringing one-year and two-year fixed terms below 6% at some lenders. One lender raised an investor variable rate by 0.05%, signalling selective tightening in higher-risk segments.
Trade-offs for borrowers chasing the low rate
A 0.5% rate cut on a $600,000 loan saves roughly $3,000 a year in interest, or $250 a month. Over two years that’s $6,000, enough to cover refinancing costs (typically $1,000 to $2,000 in application, valuation and discharge fees) and still bank material savings.
The catch: refinancing resets your loan term unless you negotiate otherwise, and some lenders claw back cashback offers or waived fees if you exit early. If the intro rate expires and you refinance again 18 months later, you’ve now paid two sets of switching costs and added 12-18 months to your total loan life.
Key numbers
- 52 lenders now offer at least one variable rate below 6%
- Lowest advertised owner-occupier variable: 5.69% (any LVR)
- Average owner-occupier variable: 6.25%
- Average investor variable: 6.48%
- Lowest investor variable: 5.94%
- Typical refinancing cost: $1,000–$2,000
Scenarios for the next 12 months
Base case: competition holds through mid-2025 as challengers chase volume before an expected wave of fixed-rate expirations hits in Q3. Rates below 5.75% stay rare but sub-6% becomes the new battleground for non-banks and regionals. Big four banks continue selective retention discounting without broad cuts.
Upside for borrowers: RBA cuts in H2 2025 push the average variable rate toward 6%, and some lenders pass through more than the cash rate move to defend market share. Sub-6% deals become standard for low-LVR, high-serviceability borrowers.
Downside: funding costs rise or credit conditions tighten, and lenders pull back intro offers or lift reversion rates faster than expected. Borrowers who refinanced into honeymoon deals face 6.5%-plus standard rates with fewer competitive options to jump to.
Red flags when comparing offers
Check the reversion rate and timeline, some lenders bury a 1.2% jump after 12 months in the fine print. Compare total interest cost over three years, not just the first-year rate. Factor in offset account availability: a 6.1% loan with full offset can beat a 5.8% loan with no offset if you carry a decent savings buffer. Confirm loan features (extra repayments, redraw, portability) before switching, losing flexibility to save 0.3% can cost more in the long run.
If you’re with a major bank, call retention before applying elsewhere. Many borrowers secure a 0.4%-0.6% discount without switching lender, avoiding refinancing friction entirely.

The practical take for refinancers
Start here: pull your current loan statement, check your rate and reversion date if you’re on an intro deal. Compare the total three-year interest cost of your current loan against the best sub-6% offer you’re eligible for, including all fees. If the saving exceeds $4,000 over three years and you’re comfortable refinancing again in 18-24 months, the switch pencils out. If you value stability or can negotiate a retention discount from your current lender, that may deliver better net value with less friction.
