  1. The table gives a summary of the attendance modes of gathered perspectives covered in this Comment. ‘Location’ indicates the institutional base of the attendee, and ‘Position’ gives whether they are student, postdoc or staff (noting that staff in this case captures a broad range of functional roles). In two EAS cases, attendees switched from ‘online’ to ‘GA only’ attendance, which meant signing up to attend the EAS General Assembly (GA) only, due to the limited provision of content via online attendance. In one ASA case (a), COVID isolation meant switching from in-person to online attendance and staying an extra week in Tasmania, which raised the costs from 2,800 Australian dollars (AUD) to over 4,600 AUD. In another ASA case (b), registration was waived, which significantly reduced the cost of attending in person. In one HVC case (c), transition from in-person to online attendance reduced costs from an anticipated approximately 4,000 AUD to 50–1,900 AUD, depending on as-yet unknown refund of flight costs after airline-caused cancellation. Thus for HVC, our in-person perspectives cover relatively local attendance and so the costs are indicative only of registration fee (including meals and accommodation at Green Bank Observatory) in the absence of additional travel costs. We have not, in this case, provided an estimate of carbon costs associated with travel, but note that costs would be negligible for online attendance, minor for local attendance, significant for domestic attendance and major for international attendance, depending on the mode of transport14. Costs in other currencies were converted to their AUD equivalent as of 27 June 2022 for ease of comparison.
