It appears that both choppers then continued to Amberley.
Of interest, one other Bell 429 helicopter was also spotted passing through Gladstone Airport but on Monday 27 June with VH-EQP of Corporate Aviation photographed soon after arriving from Wanella Station near Coppabella. After taking on fuel, it continued to its Southport base.
VH-EQP had flown North to Mackay Airport via Gladstone last Friday 24 June and must have flown West to Wanella Station over the weekend.
