JANUARY KEY POINTS
SHORT-TERM VISITOR ARRIVALS
SHORT-TERM RESIDENT DEPARTURES
This publication contains overseas movement data which should not be interpreted as 'persons'. See paragraph 5 of the Explanatory Notes for more detail.
The statistics in this publication have been rounded to the nearest 100 for short-term movements and to the nearest 10 for permanent and long-term movements. As a result, sums of the components may not add exactly to totals. Analysis featured in this publication is based on unrounded data. Calculations made on rounded data may differ to those published.
SUSPENSION OF SHORT-TERM RESIDENT DEPARTURES TREND ESTIMATES
The trend estimates have been suspended from April 2009 for all Short-term Resident Departures (STRD) series. The trend estimates will be reintroduced when more stability emerges in the underlying behaviour of passenger movements.
The trend series attempts to measure the underlying behaviour in passenger movements. In the short term, this measurement may be significantly affected by unusual influences in the original and seasonally adjusted data, like those observed between April 2009 and January 2010 for STRDs. If the trend estimates in the publication were to be calculated without fully accounting for these unusual influences, they would be likely to provide a misleading view of the underlying trend in activity. Further, if passenger movements in subsequent months are influenced by these unusual influences, it may be some time before the underlying behaviour of the series can be reliably estimated. For more details on trend estimates, please see paragraph 23 of the Explanatory Notes.
Appropriate seasonally adjusted estimates can be produced and will continue to be published as usual.

WARNING: Caution should be used when interpreting recent Short-term Visitor Arrivals trend estimates as they may be affected by unusual economic or other factors.
CHANGES IN THIS ISSUE
With the release of the January 2010 issue of Overseas Arrivals and Departures, Australia (cat. no. 3401.0), improvements were made to the seasonal adjustment of Short-term Resident Departures to Poland and to Other Southern and Central Asia for the period between 1976 and 1984. Therefore, small changes will be seen in the Total Short-term Resident Departures Seasonally Adjusted and Trend estimates for that period.
