How AusVisaTime handles visa data

This page documents what we collect, how we check it, how calculator dates are produced and where the limits begin. Home Affairs remains the source of truth.

Primary sources

Three official records serve different jobs

Each official record has a defined role. Processing times, visa rules and charges are published separately by the Department of Home Affairs.

Processing times

50% and 90% checkpoints for recently finalised applications, separated by visa and stream where available.

Open official source

Visa listing

Visa purpose, stay, eligibility, conditions and application steps for each subclass or stream.

Open official source

Visa pricing table

Current base charges and additional-applicant amounts, with stream and lodgement context where supplied.

Processing-time refresh

Changes are checked before they can replace active data

Processing-time checks are started manually by the maintainer. There is no scheduled automatic update. The dates shown describe the last recorded source update and verification, not a promise that the source is unchanged today.

Only validated changes reach active data

A failed or unusual result preserves the existing verified dataset while the change is investigated manually. The maintainer publishes a reviewed update only after structural checks and source comparisons pass.

The expected visa stream must still exist in the official catalogue.

Every mapped 50% and 90% result must be present and correctly formed.

The official publication date must follow chronological order and the current calendar.

The 90% checkpoint must equal or exceed the 50% checkpoint.

Exact day values must be finite, non-negative and paired with the official display labels.

Unusual changes are reviewed by the maintainer against the source; no automatic anomaly detector is claimed.

How calculator dates are produced

You select a visa pathway and lodgement date. AusVisaTime adds the exact number of days behind the current official 50% and 90% checkpoints to that date. Where Home Affairs displays rounded months, the interface can retain that wording while exact published day values are used for date arithmetic.

Lodgement date + current checkpoint = displayed date

The result compares your date with current published statistics. Individual outcomes continue to depend on the circumstances and assessment of each case.

What happens to calculator inputs

The calculator runs in your browser using the reviewed dataset. The selected subclass, pathway and lodgement date are not sent to a calculation server; names, passport details, TRNs, ImmiAccount credentials, email addresses and documents sit outside the calculation flow.

Calculation inputs stay in your browser. User profiles and application records sit outside the calculation architecture. Standard hosting and security systems may temporarily process request metadata while operating and protecting the service.

To understand whether the tools are helping, AusVisaTime counts a small set of anonymous actions such as opening a visa page or completing a calculation. These events contain no lodgement date, pathway answer, free text, account identifier or user profile and are handled by Vercel Analytics, subject to the provider's retention policy. These action counts are not unique visitor counts, and blocked or repeated events can affect the totals.

Different tools, different handling

Each product uses an update model suited to its source

ProductHow it is maintained
Nine processing calculators

Versioned processing-time dataset checked manually against the official guide; dates show the latest completed review.

Visa list and detail pages

Public Home Affairs visa, fee and processing endpoints with a six-hour cache; source dates are shown when supplied.

Visa finder

A manually reviewed, browser-based decision tree that narrows broad purposes and directs eligibility checks to Home Affairs.

If the source numeric percentiles contradict each other or their display labels, we retain previous records and leave the affected stream out of the calculator, tables and charts until the source is consistent. A complete review containing unresolved conflicts does not advance the catalogue verification date.

Historical records and trend methodology

We retain exact 50% and 90% day values, official display labels, stream IDs, the official publication date and the date recorded as checked by AusVisaTime. Dates use the Melbourne calendar. The chart axis uses official publication dates; a later check does not create a new official publication.

Historical Home Affairs figures retain their original recorded dates and values. Retained records are available for inspection. We do not fill missing months or backfill streams added later.

We compare the same stream across consecutive recorded publications. A stream is labelled shorter only when both checkpoints fall or one falls while the other stays unchanged; longer uses the opposite rule. If the two checkpoints move in opposite directions, the result is mixed. Rounded labels may stay the same while exact day values change. These comparisons describe the guide; they do not establish a cause or predict a pending application.

Repeated checks and corrections are appended without deleting previous records. Charts use the latest reviewed record for each publication; the downloadable history retains all raw records, revision numbers and correction notes. For 3-, 6- and 12-month comparisons, we use a recorded publication at or before the calendar target and no more than 14 days earlier. The actual source dates are displayed; without a nearby comparable record we show insufficient history.

Editorial and correction policy

ClearNative maintains AusVisaTime. We separate official source figures from our calculations and explanations, identify source and review dates, and avoid personal migration recommendations. Supporting visa information directs readers to Home Affairs for eligibility and application requirements.

To report an error, email me@clearnative.com.au with the page, stream, disputed value and official source. We check the report against that source. A confirmed data error receives an appended correction with a reason; we retain the previous record and update affected displays and exports. This is a process, not a guaranteed response time.

Limitations and corrections

Official figures describe groups of completed cases; individual timelines follow each case.

Priorities, application completeness, health and character checks, requested evidence, annual program settings and case complexity can all affect timing. If something on AusVisaTime appears wrong or stale, tell us what page and source you checked so we can verify it.
