A Lesson in Long Term Investment: Woodside Keeps on Giving, page-75

Unsure if you include myself with "those complaining", however some balance to your rationale;

OSH has a degree of political risk regarding their PNG deal and expansion - i'd say it's not a small risk either.
OSH has a good chunk of debt compared to WPL, which is certainly manageable however if the PNG deal falls through....
OSH also did a big CR during covid.

WPL has a much stronger balance sheet and neither political risk that may affect future income nor has it diluted it's SH during covid - so yes it's fair to offset those negatives and question their faster recovery.

In any case WPL will be the slow and steady horse, OSH will be quicker out of the gate but the jockey may fall.
Risk:Reward - we can certainly agree there!
