This dataset underpins Figure 3 of the December 2024 Offshore Resources Decommissioning Roadmap, detailing estimated decommissioning expenditure across Australian offshore oil and gas basins from 2023 to 2060. The table projects spending requirements (in unspecified units, likely millions of dollars) across six major regions: Gippsland (totalling $7,038m), North Carnarvon ($13,792m), Browse ($7,530m), Bonaparte ($1,259m), Canning ($675m), Bass ($277m), and Otway ($407m). Decommissioning activities are distributed across multiple five-year periods, with Browse and North Carnarvon showing the heaviest concentration of work extending into the 2050s. Total projected spending across all basins reaches approximately $31 billion, reflecting the scale of Australia's offshore decommissioning obligations
