DESCRIPTION:Contemporary  Australian social research—particularly for spec
 ific localities—faces a variety of challenges. The rapid decline in landl
 ine use and decline in telephone survey production rates means that random
  digit dialling (RDD) telephone surveys are impractical for all but the la
 rgest states. Although nonprobability online access panels offer rapid and
  inexpensive access to sample\, error is greater than probability samples 
 and regional quotas may be hard or even impossible to meet. Face-to-face s
 urveys have become more challenging as a result of the COVID-19 pandemic\,
  with the Australian Bureau of Statistics increasingly transitioning away 
 from this mode.\n\nAddress-based sampling  (A-BS) was developed in the U.S
 . as a response to the challenge of declining landline coverage. Although 
 it was eclipsed in popularity by dual-frame RDD as a response to this chal
 lenge\, it has proved to be enduring in the longer-term in the face of dec
 lining telephone survey production rates. In this paper\, we address consi
 derations in the conduct of A-BS surveys in Australia. A-BS surveys are la
 rgely insulated from the decline in telephone survey production by the use
  of mail as a primary means of contact\, typically in sequential multi-mod
 e design (push-to-web then hard copy).\n\nThe Geo-coded National Address F
 ile (G-NAF) is used as the sampling frame for A-BS surveys fielded by the 
 Social Research Centre (SRC). The G-NAF is the authoritative source of inf
 ormation on physical addresses in Australia. It combines address informati
 on from multiple official sources\, including state and territory land age
 ncies\, the electoral roll and Australia Post in one dataset. It is manage
 d by Geoscape Australia (previously the Public Sector Mapping Authority) a
 nd accessible under open data terms through data.gov.au. We provide an ove
 rview of how we draw samples from the G-NAF\, including:\n•	Reconciling r
 ecords from multiple sources.\n•	Validating the address is specific enoug
 h to be delivered to a single residence (as opposed to a block of apartmen
 ts).\n•	Appending Australia Post Delivery Point Identifiers (uniquely ide
 ntifies a physical point to which Australia Post delivers mail).\n•	Washi
 ng non-residential addresses (factory\, car space\, office\, shed\, etc) a
 nd deduplicating addresses.\n•	Statistical sampling to achieve an even di
 stribution within strata.\n•	Using expected stratum-level response rates 
 to estimate the final achieve sample.\n\nWe also describe field methods. T
 he SRC has used two different protocols with differing levels of response 
 maximisation based around engagement and reminder activities. \n\nFinally\
 , we address strengths and weaknesses of A-BS using the G-NAF. Strengths i
 nclude higher response rates than are possible under a telephone design\, 
 likely greater longevity than telephone surveys and ability to target smal
 l areas. Weaknesses include high cost (particularly for designs that seek 
 to maximise response rates)\, over-representation of older adults\, the mo
 re highly educated and women\, extended time in field and difficulties imp
 lementing within-household selection procedures.\n\nRecording link: https:
