National Visitor Survey (NVS) Methodology 2019 Onwards
With 97% of the Australian population aged 15 years or more owning a mobile phone, Tourism Research Australia transitioned NVS sampling to 100% mobile phone interviewing and discontinued landline sampling in 2019.
This change has improved the accuracy of national, state and territory estimates.
However, the transition from the 50% mobile phone/50% landline split resulted in an unavoidable break in series between data for 2019 onwards and earlier NVS data.
It should also be noted that Year ending March 2020 estimates are based exclusively on mobile interviewing whereas March 2019 estimates use a mix of 100% mobile interviewing (March quarter 2019) and 50/50 mobile and landline interviewing for the June through December quarters of 2018.
Please use caution when making comparisons between year ending March 2020 estimates and those from the previous year and earlier periods, as the methodology change is likely to affect results.
Note that 2017 and 2018 estimates were also revised in 2019 to align with the latest release of ABS population projections that are used to benchmark NVS results to the Australian population. Therefore, the new estimates for these years differ from previously published figures.
