CHANGES IN THIS ISSUE
From August 2015 onwards, the Department of Immigration and Border Protection (DIBP) has progressively rolled out new technologies to streamline and strengthen border operations. Departure SmartGates are currently in use at Kingsford Smith (Sydney), Eagle Farm (Brisbane), Tullamarine (Melbourne) and Darwin airport for processing passengers leaving Australia. Passengers using Departure SmartGates are required to place their outgoing passenger card in drop boxes located near the Departure SmartGate rather than handing them to Australian Border Force officers.
Coinciding with the roll-out of Departure SmartGates, there has been an increase in outgoing passenger cards not being collected due to passengers failing to place their cards into the drop boxes. The ABS and DIBP have been working together to mitigate this issue and to minimise the impact on data quality.
For April 2016, the ABS added 142,570 records to account for missing outgoing passenger cards. The ABS also added 656 records to account for a higher level of missing incoming passenger cards. A total of 143,226 missing records were added to the overseas arrivals and departures data for April. For further information see Section 7 of the Data Quality Issues (Appendix 2) in the left hand side navigation bar under the Explanatory Notes tab.
Biennial Seasonal Adjustment Reanalysis
The seasonally adjusted and trend series have been updated following the review of the seasonal adjustment process. This review confirms the extent to which movements are affected by seasonal or irregular influences. As a result, the seasonally adjusted and trend estimates of a number of series have been revised. See paragraph 28 of the Explanatory Notes for more detail.
Unreliable seasonal adjustment: In using the seasonally adjusted series, care should be exercised because of the difficulties associated with reliably estimating the seasonal pattern for the following short-term resident departure series: Other North-East Asia and United Arab Emirates. These series will be revised during the next biennial seasonal adjustment reanalyses.
