Your loan
Rates default to today's indicative carded rates (as at 30 June 2026) — editable, since an adviser prices your real options.
Each part
Why split?
Fixing the whole $600,000 on 1 year would be $1,518/fn at 5.19% — but the entire loan then rolls over at once. A split means only part of it re-prices at each rollover, so a bad rate day can't hit all of your loan. The trade-off is a slightly higher blended rate for lower timing risk.
