These two sit either side of Golden Grove Road and get overlooked in favour of their flashier neighbours. One of them has something almost nowhere else around here can offer, and it has nothing to do with the house.
The prices
Both sources, both periods, kept separate because they measure different things:
| Measure | Hope Valley | Surrey Downs |
|---|---|---|
| Median, June quarter 2026 Valuer-General SA |
$928,750 22 sales, +7.9% |
$850,000 12 sales, +12.9% |
| Median, 12 months to June 2026 Cotality |
$870,000 91 sales, +5.1% |
$835,000 54 sales, +16.8% |
Hope Valley is the dearer suburb on both measures — by about $79,000 on the quarter, $35,000 over twelve months. That's a more consistent gap than you get between St Agnes and Ridgehaven, where the two sources actually swap the order around.
But look at the growth rather than the level. Surrey Downs is up 16.8% over twelve months against Hope Valley's 5.1%. Hope Valley is the established, steadier suburb; Surrey Downs is the one closing the gap. If you bought in Surrey Downs a year ago you've done considerably better on paper.
One honesty note on those Valuer-General figures: twelve and twenty-two sales in a quarter is a thin sample, and the Valuer-General says so itself — short-term suburb movements "should be viewed with caution". The twelve-month numbers, built on 91 and 54 sales, are the ones I'd lean on for a trend.
The thing nobody mentions: Hope Valley is not split
Almost every suburb around here has a high school zone boundary running through it. Ridgehaven, Redwood Park, St Agnes, Modbury Heights, Surrey Downs — in all of them, two houses in the same suburb can be zoned to different schools.
Hope Valley
Sits entirely within the Modbury High School zone. Wherever you buy in the suburb, that's your zoned high school. No boundary to fall the wrong side of.
Surrey Downs
Split between The Heights School and Golden Grove High School. Which one you get depends on the address, not the suburb — so it genuinely has to be checked before you make an offer.
That's a real, checkable difference, and it's the kind of thing that only shows up when you look. If certainty about schooling matters in your household, Hope Valley removes a variable that almost every neighbouring suburb leaves open.
On primary schools, both are mostly unzoned — placement comes down to the closest unzoned school by road. Part of Surrey Downs falls inside Golden Grove Primary's zone, and part of Hope Valley inside Ardtornish Primary's. Worth knowing that Highbury Primary and Modbury South Primary are both physically located in Hope Valley, despite their names. The full school zones guide has the thirty-second address check.
What they're actually like
Similar housing stock to most of the north-east — predominantly three and four bedroom homes on decent allotments, largely 1970s and 80s, heavily owner-occupied.
- Hope Valley is the older, more established of the two, closer in toward Modbury and the Tea Tree Plaza end of things. Bigger blocks in parts.
- Surrey Downs is newer, sitting up against Golden Grove, and tends to attract buyers who want the Golden Grove area without the Golden Grove price.
That last point is the whole story of Surrey Downs' growth number. At $850,000 it is about $83,000 under Golden Grove's $933,500 for the same quarter, and it borders it. Buyers priced out of one have been moving to the other, which is exactly what you'd expect when borrowing capacity tightens.
Which one would I point you at?
Hope Valley if schooling certainty matters, if you want the more established streets, or if you're buying to hold for a long time and want the steadier of the two.
Surrey Downs if you want to be next to Golden Grove without paying for it, or if you're weighing recent growth most heavily. Just check the school zone on the actual address before you commit to anything.
And the usual caveat, which matters more than the suburb choice: the spread between individual houses inside either suburb is wider than the spread between the two suburbs. Buy the right house.
How I worked this out
Prices are from two independent sources, each shown with its period: the Office of the Valuer-General's published quarterly sales data, free via data.sa.gov.au, and Cotality's rolling twelve-month figures. They're in separate rows rather than blended, because one is a single quarter and the other a twelve-month average, and in a rising market the quarter runs ahead.
Zoning is from the Department for Education's live zone service for the 2026 enrolment year. I've said which schools each suburb falls to without putting a percentage on it — the only number that counts is what the department's finder says about your address.
The comments on character, blocks and who buys where are my own read from working these suburbs, and I've labelled them as that rather than dressing them up as data.
The bottom line
Hope Valley is dearer and steadier. Surrey Downs is cheaper and growing faster, mostly because it borders Golden Grove and costs considerably less.
The difference most people miss: Hope Valley sits wholly inside one high school zone, which almost nowhere else around here does. Surrey Downs is split.
If you want the number for a specific house in either, that's a short conversation and I'll show you the evidence behind it.
