Web Development Company in Sydney

Where you land depends on which of these you commission: a scoped Sydney marketing or content site on Next.js or Astro, a production web application (customer portal, internal SaaS console, retail headless storefront), or CDR-ready open-banking journeys on FAPI 1.0 Advanced, full Service NSW-style citizen portals, and complex Atlassian or Canva-grade web platforms. Scope drivers include a Sanity or Storyblok CMS, a WCAG 2.1 AA accessibility pass, and a Privacy Act 1988 data map. Sydney rates sit above Brisbane and Adelaide because of the Atlassian, Canva, and Big Four banking talent premium. We provide fixed-fee proposals rather than open time-and-materials estimates.

Every Sydney engagement opens with a Privacy Act 1988 and Australian Privacy Principles data-flow workshop, mapping every personal-information touchpoint, retention window, and overseas-disclosure path. We design against the 2022 and 2023 reforms that lifted serious-breach penalties past AU $50M, and we ship an eligible-data-breach response runbook aligned with the OAIC's Notifiable Data Breaches scheme, including the 30-day assessment window and notification templates. Authentication, logging, and PII redaction follow the OAIC's reasonable-steps guidance, and we feed audit logs into a SIEM that your privacy officer can query without a developer in the room. The result is a web platform whose privacy posture survives an OAIC investigation, not just a launch-day press release.

Yes. We design and build Consumer Data Right (CDR) data-sharing journeys for Australian banks, energy retailers, and accredited data recipients across Open Banking, Open Energy, and the emerging Open Telco regime. Builds target FAPI 1.0 Advanced with mTLS, PAR, JARM, and PKCE, and integrate with the ACCC Conformance Test Suite and the Data Recipient and Data Holder registers. We pattern consent UX against published Macquarie, CBA, Westpac, and Frollo flows, log every consent and revocation against CDR record-keeping obligations, and ship a Consumer Data Standards conformance report your CDR accreditation reviewer can lodge as-is. We also build the dashboards consumers use to manage active arrangements, which is where most CDR programs lose users.

We build to WCAG 2.1 AA as the contractual baseline, which is the mandate for Australian Government digital services under the Australian Government Web Guide and the practical threshold for Disability Discrimination Act 1992 risk on private-sector sites. NSW government engagements transition toward WCAG 2.2 AA where procurement specifies it, and complex Service NSW or Service Australia patterns inform our component library. Every release ships with an automated audit (axe-core, Lighthouse), a manual keyboard and screen-reader pass using NVDA and VoiceOver, and an optional independent review by the Vision Australia Digital Access Service for procurement-grade sign-off. Accessibility lands in design tokens and Storybook from sprint one, not bolted on at user-acceptance testing.

We default to AWS ap-southeast-2 (Sydney) as the primary region for storage, compute, and CDN origin, with ap-southeast-4 (Melbourne, launched in 2023) for active-active failover when an APRA CPS 230 operational-risk tier demands it. Azure Australia East (Sydney) is the default for Microsoft-aligned enterprises, and GCP australia-southeast1 (Sydney) suits clients already running BigQuery or Vertex AI in country. Edge sits on Cloudflare Australia or CloudFront ap-southeast-2 POPs. Cross-border transfers occur only when an Australian Privacy Principle 8 assessment signs off, and the result is documented in the data-processing agreement so OAIC and APRA reviewers have a single source of truth rather than a Slack archaeology project.

Sydney media, marketplace, and social platforms operate under the Online Safety Act 2021 and the eSafety Commissioner's expectations on cyber abuse, image-based abuse, illegal and restricted content, and the Basic Online Safety Expectations. We build moderation, reporting, and takedown workflows that meet the 24-hour and 48-hour removal windows depending on notice type, integrate trusted-flagger pipelines for News Corp, Nine, and Guardian Australia style mastheads, and log moderation decisions in a format the eSafety Commissioner accepts during compliance reviews. We also build the transparency surfaces that BOSE-aligned providers now publish, so your platform never has to retrofit an audit trail after a public eSafety determination.

Yes. APRA CPS 234 (information security) and CPS 230 (operational risk management), in force from 1 July 2025, drive how we build for Sydney banks, insurers, super funds, and authorised non-operating holding companies. CPS 234 work includes information-asset classification, vulnerability and threat-management cadence, incident response within APRA-defined notification windows, and third-party assurance over our own development environment. CPS 230 work adds critical-operations mapping, severe-but-plausible scenario testing, business-continuity tolerance levels, and material-service-provider documentation. We ship the artefacts your internal audit team and APRA prudential supervisors actually request, and we coordinate with your CISO on annual independent reviews.

Web work that involves genuine technical uncertainty (novel rendering architectures, performance research, CDR conformance engineering, accessibility automation, real-time orchestration) often qualifies for the R&D Tax Incentive, administered jointly by AusIndustry and the ATO. Eligible companies under AU $20M aggregated turnover receive a 43.5 percent refundable offset on eligible R&D expenditure, and larger entities receive a 38.5 percent non-refundable offset above the corporate tax rate. We deliver time-tracked engineering logs, hypothesis and experiment records, and failed-attempt documentation aligned with the AusIndustry registration form. Routine integration and standard CMS configuration do not qualify, and final eligibility sits with your R&D Tax Incentive consultant. NSW Investment Attraction and Export Market Development Grants may stack for export-oriented platforms.
