The verdict in three sentences
In Adelaide, redesigning a luxury real estate agency website costs a 2026 ballpark of AUD 12,000 to 30,000 (about USD 7,800 to 19,500) with a local agency for an English site, and each extra language often adds AUD 4,000 to 10,000. At Kolonell, Growth at USD 4,900 covers a full English site and Premium at USD 8,900, the multilingual tier with languages set in the quote, covers the international buyer journey. The main risk of a multilingual redesign is technical: without consistent hreflang tags and a 301 redirect map, you lose both your English rankings and the visibility of the new language.
Who is the new site really for?
Buyers in Unley Park, Springfield, North Adelaide or the Adelaide Hills increasingly include professionals relocating to the city, notably in defence and health, and buyers discovering the city from overseas. An agency that also runs a small lettings book also hears from landlords and prospective tenants.
| Visitor | What they look for first | Page or feature | Language |
|---|---|---|---|
| Defence professional on a posting | Suburbs, schools, commute | Suburb guides | English |
| Clinician arriving from the UK or Europe | The buying process explained simply | Buying in Adelaide page | English, sometimes another language |
| Overseas buyer | Video tour, contact in their time zone | Listing page with video, short form | Language of their home market |
| Local vendor | Appraisal, the agency's approach | Appraisal form | English |
| Landlord | Management fees, reporting | Property management page | English |
| Prospective tenant | Available rentals, how to apply | Link to a secure application platform | English |
This table sets the scope: if your overseas visitors come mainly from one or two markets, one extra language done well beats four machine translations.
What does a multilingual redesign cost in Adelaide?
Indicative ranges based on typical South Australian agency quotes and public Australian agency rate pages, converted approximately to USD (at about 0.65). The local maintenance figure is a market assumption.
| Scenario | Local agency (ballpark) | Kolonell | Note |
|---|---|---|---|
| English only, sales and lettings | AUD 12,000 to 30,000 (about USD 7,800 to 19,500) | Growth USD 4,900 | Suburb and property management pages included |
| English plus one language | AUD 16,000 to 40,000 (about USD 10,400 to 26,000) | Premium USD 8,900 | Languages set in the quote |
| English plus two languages | AUD 20,000 to 50,000 (about USD 13,000 to 32,500) | Premium USD 8,900, scope set in the quote | Native review advisable, as a third-party cost |
| Compact brochure site | AUD 5,000 to 10,000 (about USD 3,250 to 6,500) | Starter USD 2,900 | No detailed suburb pages |
| Maintenance over 3 years (market assumption) | AUD 200 a month × 36 = AUD 7,200 (about USD 4,680) | 3 months included, then on quote | Compare like for like |
| realestate.com.au and Domain feeds, CRM | AUD 2,000 to 8,000 (about USD 1,300 to 5,200) | On quote | Always a separate line |
Every tier includes a project manager reachable in your time zone, native English or French copywriting and delivery in 3 to 4 weeks once content is ready. Photos, video, drone and floor plans come from a local photographer as a third-party cost.

How do you get hreflang and the migration right?
A multilingual version adds a layer of risk to a standard redesign. Here is the typical timeline and the multilingual checks.
| Phase | Weeks | Deliverable | Multilingual check |
|---|---|---|---|
| Audit and URL inventory | 1 | List of pages receiving traffic, Search Console export | Structure chosen: one subfolder per language |
| Content and translation | 1 to 2 | English copy, then the added language | Suburb pages adapted, not just translated |
| Build and staging | 2 to 3 | Templates, forms, language switcher | Reciprocal hreflang tags and x-default |
| Compliance review | 3 | Marketing statements and forms reviewed | Same information in every language |
| Cutover and monitoring | 4 | 301 map live, one sitemap per language | Indexing report per language for 14 days |
The rules to remember: every page points to all its versions and to itself; no automatic redirect by IP address, visitors choose their language; sold listings are archived or redirected in every language; currency and phone number formats are clear to an overseas buyer.
Rental applications collect far more personal data: they must go through a secure platform, never through an open form on the site. For purchase enquiries, stick to name, contact details, property reference and an optional budget range. The Privacy Act 1988 generally applies to businesses above AUD 3 million in annual turnover, with exceptions; Australian Consumer Law prohibits misleading advertising; South Australia has its own licensing and price statement rules. FIRB rules for foreign buyers and anti-money-laundering checks belong to the agency's process. This is not legal advice.

When is an Adelaide agency the better choice? If you want to meet the team every week, if your property management software requires a locally certified integrator, or if your overseas market calls for an agency that knows its culture from the inside. Ask any provider: what URL structure per language? Who checks hreflang after launch? Who translates and who reviews?
Mini case study
Illustrative example. Hillsview Residential, an Adelaide agency combining high-end sales with a small book of 40 managed properties, wants English plus one extra language. Its site has 25 core pages and 12 suburb pages, so 37 pages × 2 languages = 74 URLs to link with hreflang, plus 37 old URLs to redirect. The agency picks Premium at USD 8,900 (the multilingual tier, languages set in the quote) and plans a review by an independent native speaker as a third-party cost. Against a local quote of AUD 30,000, about USD 19,500, the gap is roughly 19,500 minus 8,900 = USD 10,600, before portal feeds, which stay on quote on both sides.
FAQ
Do we need to translate the whole site?
No. Translate first the pages overseas buyers read: suburb guides, buying process, listings, contact. On a 37-page site, 15 to 20 translated pages are often enough at launch.
What is hreflang and why is it critical?
It is a tag telling Google which language version to show to which visitor. Without reciprocal hreflang on 100% of translated pages, the two versions can compete against each other in results.
Which Kolonell tier fits a multilingual site?
Premium at USD 8,900, the multilingual tier with languages set in the quote. An English-only site fits Growth at USD 4,900.
How long does a multilingual redesign take?
Three to four weeks with Kolonell once content is ready, plus 1 week if translations arrive late. Local agencies often quote 10 to 16 weeks.
Can rental applications go through the website?
The site can link to a secure application platform, but it should not collect ID or proof of income in an open form. Keep site forms to 4 or 5 fields.
