I'd love to get into Sydney Airport and hold long-term until life resumes as normal but I'm struggling to put a value on it. There won't be international flights (which bring in 4 x the revenue of domestic passengers -- I think it's four times...) for six months? 12 months? Who knows. There won't be distributions this year; maybe not next year either. There's the risk of dilutive money raising. I can't work out if it's cheap or expensive; whether it should be at $6 or $3. Each time I think I'm going to buy the price either starts to increase quickly or decrease quickly!
