There are no direct flights. Qantas will take you there via Johannesburg (code-sharing with SAA). With adjustments for the time zones you'd arrive in Sydney 24 hours after departing Lagos... but in actual elapsed time (time zone changes and stopovers included) it's more like 39 hours.
That would put you at great risk of a DVT, so make sure you get up and walk around on the flights. perhaps consider breaking the journey into 2 parts and have a night's rest in Johannesburg. Much better for your health.

Yes it is a long journey from Lagos to Australia. Last year, I had to travel from London to Lagos and then from Lagos to Sydney. Usually I get my tickets from reliancetravels (dot co dot uk) but this time I had changed my travel agency. From London to Lagos, My seat was near toilet and I could not sleep throughout the journey because I was feeling as if I were sitting on a pavement. My advice to you is whenever you travel from or to Lagos, book your seats through a reliable resource otherwise, you might by ripped. almost 3 years ago
