NSW council rates 2026-27: which councils went furthest above the cap

The cap is a ceiling for most councils, and a floor for some

Most NSW ratepayers assume their council rates cannot rise by more than the peg IPART sets each year. That is true by default, but a council can apply to exceed it. If IPART approves a special rate variation, the peg stops applying and the approved SRV percentage replaces it, usually to fund an infrastructure backlog or restore financial sustainability. For 2026-27, IPART approved general-rate SRVs affecting residential ratepayers in 7 councils.

By percentage, Ku-ring-gai and Uralla Shire went furthest. Ku-ring-gai's average residential rate rises 29.0% for 2026-27 (a 24.6% SRV component stacked on its 4.4% peg), from about $1,697 to about $2,189, funding stormwater drainage, footpaths and a new indoor sports centre. The council puts the increase at roughly $499 a year for the average ratepayer. Uralla, a small rural council in the New England region, was approved for 28.5%, with a further 23% flagged for 2027-28. Both are more than five times what their own standard peg would have allowed.

The more surprising name is North Sydney, a small, affluent harbourside council, not the kind of area most people expect to see leading a rates story. Its permanent SRV lifts the average residential rate 23.3% in 2026-27 alone, from $1,076 to $1,327, a $251 increase and the second largest of the seven behind Ku-ring-gai. IPART's own capacity-to-pay assessment found the area has a high level of financial advantage compared to other Sydney and regional councils, which was part of why the application succeeded. The rise continues: 14.2% in 2027-28 and 8.2% in 2028-29, taking the cumulative increase to 52.3% and the average rate to $1,638 by then, funding what the council describes as long-standing under-investment in infrastructure renewal.

NSW councils approved to exceed the rate peg, 2026-27

Every figure below is the average residential general rate reported for that council, using each council's own 2025-26 baseline and its confirmed 2026-27 increase. This is the fairest comparison across councils because it reflects the actual mix of properties being rated, not a single minimum figure.

Blacktown's figures reflect what the council actually adopted for 2026-27, 11.5%, rather than the fuller 15% first-year rise it originally proposed; council retains discretion to phase in less than IPART's approved ceiling. Every other council on this list adopted its full approved increase for the year.

Where the cap held, and two that only look like it did not

The councils that exceeded the peg split into two groups. North Sydney, Ku-ring-gai and Hawkesbury are established Sydney metro councils funding infrastructure renewal after years of deferred maintenance. Blacktown, one of Sydney's fastest-growing council areas, is funding new and upgraded community facilities to keep pace with population growth. Uralla and Glen Innes Severn are small regional New England councils where a modest budget gap translates into a large percentage rise, the same pattern behind Somerset's standout increase in Queensland's 2026-27 rates. Ballina's rise is the smallest of the seven, a modest 6% a year running through to 2029-30.

Most councils stayed within their own peg. Of the 126 NSW councils in SuburbCost's data, 119 had no approved general-rate SRV for 2026-27, meaning their residential rates rose by their individual peg only, somewhere between 2.7% and 5.7%.

Central Coast and Muswellbrook are not really part of this story, despite both appearing in "special variation" news coverage for 2026-27. Central Coast's approval lets it move the existing Stormwater Drainage Charge from being levied under the Water Management Act to being levied as a general rate under the Local Government Act, a reclassification of an existing charge, not a new increase on top of the peg. Muswellbrook's approved 25.9% SRV applies exclusively to its Mining-General and Mine Rehabilitation rate categories; residential, farmland and business ratepayers there are capped at the standard 3.1% peg like everyone else without an SRV.

Which NSW councils charge the most, and the least

Rate rises are one story. The level you actually pay is another, and the gap between the top and the bottom of the state is far wider than any single year's increase. The dearest council area in New South Wales charges about 17 times the cheapest.

The top of the list is not the list most people expect. Hunters Hill is a small, affluent harbourside council, but Cobar sits second and it is a remote mining town in the state's far west, roughly 700 kilometres from Sydney. Wollondilly, Blue Mountains and Wingecarribee are all semi-rural fringe councils covering large areas with dispersed populations, which is expensive to service per household. Being expensive to run has more to do with how far the roads and pipes stretch than with how wealthy the residents are.

The cheapest council areas are all in far-western NSW, where land values are low and the rate base is small. A $144 average rate in Brewarrina is not a bargain in any practical sense: it reflects a council with very little to tax, not a cheaper place to live. Groceries, fuel and insurance generally run higher out there, which is why the rates line on its own is a poor guide to what a suburb costs to live in.

The NSW median sits at $1,282. Half of the 126 councils charge more than that and half charge less, and most of the metro Sydney councils people assume are expensive land closer to the middle of the table than the top.

Ku-ring-gai, fourth on this list, is the one that moved most to get there. Its 29% special rate variation added about $492 to the average bill in a single year, the largest rise of any NSW council for 2026-27, and it was already above the state median before that.
