Note 1
Coverage and active listings
The market pages count distinct, currently active Australian roles classified under Information & Communication Technology or one of its direct specialisations. The calculation reads Xprt Jobs' active-listing statistics view; expired and inactive listings are outside the snapshot.
Coverage depends on the sources currently collected, their publication patterns and how well each listing can be classified. It is not a census of every vacancy or worker in Australia, and a change in source coverage can move a figure even when employer behaviour has not changed.
Note 2
Advertised salary evidence
Salary measures use listings with a usable advertised remuneration range. Annual, monthly, daily and hourly amounts are normalised to an annual Australian-dollar basis using fixed cycle multipliers. The median and the 25th to 75th percentile range describe that observed advertised-pay sample; they are not an estimate of total compensation or of what everyone working in the field earns. Salary figures are shown to the nearest $100, because the percentiles fall between advertised salaries.
The salary strip draws the same sample as bands of advertised pay. The bands cover unequal ranges, so each bar's height shows its share of listings per $10k of pay it spans, and a wide band is not drawn taller for covering more of the range. The yellow marker is the median and the dashed lines are the lower and upper quartiles.
Xprt Dev collects only advertisements that state their pay. A listing whose advertised salary cannot be read is recorded so it is not fetched again, and is never published into the inventory these pages measure. Every figure here therefore describes the part of the market that advertises pay, which is a subset of all advertised roles, and a share of listings carrying pay would always be one hundred per cent.
Salary measures count each listing once, even when it is advertised in more than one place, so a listing advertised widely carries no more weight than one advertised once.
Note 3
30-day movement
The ICT overview fits a linear trend across the daily active-listing snapshots held for the previous 30 days and requires at least seven of them. The fitted slope is scaled to a month, so the figure is a rate of movement rather than the difference between the count today and a count taken 30 days ago, and the window holds fewer than 30 days while snapshots are still accumulating. A calculated change above 2% is labelled up, below -2% is labelled down, and the range between them is labelled stable.
This describes movement in observed active listings. It does not predict future demand. Specialisation pages leave the trend out because the current series rolls up to broad ICT and must not be presented as if it were specific to a child classification.
Note 4
Advertising organisations
Organisation counts are distinct active listings associated with each advertiser in the selected market. They are ranked by active listing count, and the page shows only the leading organisations. An advertiser is either the employer or a recruitment agency, and an agency may be recruiting for employers it does not name, so its count can gather several employers' roles. A count indicates visible hiring activity in Xprt's inventory, not headcount, hires made or employer size.
Note 5
Breakdowns and refresh
Work-arrangement and employment-type breakdowns include only listings with a usable value for that field, so their totals can differ from the headline active-role count. A listing advertised in more than one place counts once for each place in the work-arrangement breakdown. While a market holds fewer listings than the minimum sample, its breakdowns and organisations are withheld, as its salary figures are, rather than shown as shares of one or two listings. Listings may be edited, removed, duplicated at source or classified imperfectly.
The active-job statistics view is scheduled to refresh every 15 minutes, and daily snapshots feed the 30-day trend. A delayed source, a failed refresh or a catalogue change can make the displayed data older or temporarily unavailable, so the schedule is not a guarantee that every figure is exactly 15 minutes old.
Note 6
Xprt Dev and Xprt Jobs
Xprt Dev owns the market view and these notes. Xprt Jobs owns job search, job detail, applications and employer services. "View jobs on Xprt Jobs" opens the stable Australian category page; it does not promise a shared login or carry an application across.
Note 7
Corrections
If a figure looks wrong, email [email protected] with the page URL, the figure, when you saw it and why it concerns you. We review the source and the calculation, correct confirmed errors, and never quietly widen a sample to make a metric appear available.
