1. The Ultra-High Tier: Eastern Suburbs (Est. 4,500 – 6,000 homes)
This region contains the highest dollar-value and volume of pre-1985 CGT exempt assets due to multi-generational family wealth, large estate holding patterns, and a highly affluent demographic that rarely needs to liquidate primary assets.
- Vaucluse / Rose Bay / Watsons Bay: ~800 – 1,100 homes
- Bellevue Hill / Double Bay: ~600 – 800 homes
- Woollahra / Centennial Park: ~500 – 700 homes
- Randwick / Coogee / Clovelly: ~900 – 1,200 homes
- Paddington / Darlinghurst: ~300 – 500 homes (High building volume, but historically very high property churn, which heavily reduced the active tax exemptions).
2. The High Tier: Upper & Lower North Shore (Est. 4,000 – 5,500 homes)
The North Shore is dominated by grand Federation, Inter-war, and mid-century homes. The average holding period in these leafy, family-oriented suburbs is among the longest in metropolitan Sydney.
- Mosman / Cremorne / Neutral Bay: ~700 – 950 homes
- Wahroonga / Turramurra / Pymble: ~800 – 1,100 homes
- Killara / Gordon / Lindfield: ~600 – 800 homes
- Castlecrag / Willoughby / Northcote: ~400 – 600 homes
- St Ives / Roseville: ~500 – 700 homes
3. The Upper-Middle Tier: Inner West (Est. 3,500 – 4,800 homes)
The Inner West features two distinct categories of long-term owners: strict heritage-protected pockets, and a significant demographic of European post-war migrant families who bought homes in the 1960s/70s and have “aged in place.”
- Haberfield / Five Dock: ~600 – 850 homes (Haberfield’s strict “no-demolition” heritage protection acts as a massive tax-shield locker).
- Marrickville / Dulwich Hill / Petersham: ~700 – 900 homes
- Strathfield / Burwood: ~500 – 700 homes
- Balmain / Birchgrove / Leichhardt: ~400 – 600 homes
- Ashfield / Croydon: ~400 – 550 homes
- Newtown / Erskineville: ~200 – 350 homes (High volume of old terraces, but massive buyer turnover since the 1990s has wiped out most exemptions).
4. The Middle Tier: Northern Beaches (Est. 2,000 – 3,000 homes)
While the Northern Beaches has a massive volume of houses built in the 1960s and 70s, extensive luxury renovations and property handovers to next-of-kin have stripped many homes of their pre-1985 tax identity.
- Manly / Clontarf / Fairlight: ~350 – 500 homes
- Avalon Beach / Palm Beach / Whale Beach: ~300 – 450 homes
- Balgowlah / Seaforth / Manly Vale: ~300 – 400 homes
- Frenchs Forest / Forestville / Belrose: ~400 – 550 homes
- Newport / Mona Vale / Narrabeen: ~250 – 400 homes
- Dee Why / Brookvale / Curl Curl: < 150 homes (Dominated by 1970s apartment blocks that change owners frequently).
5. The Lower-Middle Tier: Southern Sydney & St George (Est. 1,800 – 2,500 homes)
Mainly centered around the long-held premium waterfront tracks of the Georges River and the original suburban blocks of the Sutherland Shire.
- Cronulla / Woolooware / Burraneer: ~350 – 500 homes
- Kangaroo Point / Kyle Bay / Blakehurst: ~250 – 350 homes
- Hurstville / Penshurst / Mortdale: ~300 – 450 homes
- Gymea / Miranda / Caringbah: ~300 – 450 homes
6. The Low Tier: Established Greater West & South-West (Est. 1,000 – 1,800 homes)
Suburbs in these regions boomed heavily in the 1970s. However, because these areas served as standard “stepping stone” suburbs for growing families upgrading or relocating over a 40-year window, property turnover was historically very high.
- Blacktown (Older pockets) / Lalor Park: ~200 – 350 homes
- Penrith (Older pockets) / Kingswood: ~150 – 250 homes
- Parramatta (Suburban fringe) / Granville: ~150 – 250 homes
- Liverpool (Established) / Cabramatta: ~150 – 250 homes
- Bankstown / Revesby: ~200 – 300 homes
7. The Zero Tier: Modern Growth Corridors (Virtually 0 homes)
In these areas, the pre-1985 exempt volume is essentially zero. These suburbs consist of master-planned communities, high-density residential high-rises, or newly carved-out greenfield land package estates.
- The Hills District (Newer sectors): The Ponds, Kellyville, Rouse Hill, Box Hill, Gables.
- South-West Growth Sector: Oran Park, Gregory Hills, Leppington, Edmondson Park.
- North-West Infrastructure Belts: Marsden Park, Schofields, Riverstone.
- High-Density CBD Nodes: Green Square, Olympic Park, Macquarie Park, Parramatta CBD.
⚠️ Final Notice: The Exemption Sunset Clause (July 1, 2027)
Following the Federal Budget, the blanket pre-1985 CGT exemption is officially being abolished on July 1, 2027. If you are looking at these properties from an investment, estate planning, or auditing perspective, note the transitional rules:
- Fully Exempt Window: Any property sold before June 30, 2027, remains 100% CGT-free under the legacy rules.
The Deemed Cost-Base Reset: If a pre-1985 property is held past July 1, 2027, its capital gains tax clock effectively resets. The owner must get a formal market valuation on July 1, 2027, which becomes the property’s new “cost base.” Any capital gains made from that day forward will be taxed under the newly reintroduced CPI-indexation method with a minimum 30% tax floor.

The pre1985 houses purchases Capital Gain Tax exemption cancellation is turning point for Australia’s tax system
Several factors have aggressively diluted this pool over the last four decades:
- Property Turnaround: The average hold period for a house in Sydney is roughly 9 to 12 years. Very few properties survive 40+ years without being sold.
- Intergenerational Transfers: If a parent purchased a home in 1980 and passed away in 2010, leaving it to their children, the pre-CGT status is often reset or modified upon inheritance.
- Corporate/Trust Changes: If a company or trust bought the property before 1985, but the majority ownership of that company changed by more than 50% since then, the ATO strips the pre-CGT status.
- Major Renovations: If a pre-1985 home undergoes a massive knock-down rebuild or a substantial renovation, the ATO treats the new structure as a separate, modern asset subject to CGT, even if the land remains exempt.
