*2.6. Informal and Semi-Structured Interviews*

Nineteen informal interviews (Table 1) along both supply chains were undertaken to understand the decision-making of supply chain actors and how these factors influenced postharvest losses. Interviews were conducted on-farm concurrent to the quantitative assessment, as farm workers went about their daily duties, with each interview lasting up to 20 min. Following the supply chain assessments, five semi-structured interviews (Table 2) with key supply chain actors and industry specialists were undertaken to reflect on findings and investigate the drivers and impacts of FLW, specifically drawing on the role of technology, supply chain length, and private food policy and standards. With participant consent, all interviews were audio-recorded and transcribed verbatim. Standard thematic analysis techniques were used, supported by NVivo qualitative data analysis Software (QSR International Pty Ltd., version 11.4.0). All subjects gave their informed consent for inclusion prior to participation in the study. The study was conducted in accordance with the Declaration of Helsinki, and the protocol was approved by the Ethics Committee of the University of the Sunshine Coast (HREC S/14/691).

No statistical analysis was undertaken in this case study as data was based on overall actual loss at each point along the chain, rather than replicated mean sub-sampling. This approach is consistent with recent FLW studies [44–46] and reflects an emphasis on comparative loss along the chain rather than specific loss.
