"How long will it take to get data?" is a common question that is asked of all of the data linkage units within the PHRN. Whilst we there is no single answer to this question, there are some common factors that influence how long it takes to get data. These factors also impact costs. The following table summarises known factors that impact project timeframes and costs.

Costs and timeframes summary

In Australia, all research projects using linked data must be first submitted to the data linkage unit to be assessed for technical feasibility. Formal approval must then be obtained from:

  1. The data custodian responsible for each data set; and
  2. All relevant Human Research Ethics Committee(s) (HREC).

Additional approvals may be required, depending on the data collection(s) involved and/or the jurisdiction. The approvals required for each data collection are listed in the  .

The process of obtaining approvals and the time involved will vary between data linkage units, data custodians and HRECs. The following table summarises known factors that impact project approval timeframes.
