There are two misconceptions in this question.
First, there are no egg-laying marsupials. All marsupials give live birth.
Second, there are numerous venomous mammals. Many species of shrew, as well as the Cuban Solenodon, are venomous mammals.
The only egg-laying mammal that is venomous is the platypus, which ejects venom through a hollow spur on each ankle. Only maturemales have spurs and can eject venom. The platypus is a monotreme, not a marsupial. Monotremes are egg-laying mammals.

Is the platypus the only poisonous marsupial?
No, because the platypus is not a marsupial. A platypus is a monotreme (egg-laying mammal). It is not the only venomous mammal. "Venomous" is the correct term, rather than "poisonous", as things which are poisonous must be ingested, i.e. eaten or drunk. Other venomous marsupials include the Cuban solenodon, Eurasian Water Shrew, Northern Short-tailed Shrew and Southern Short-tailed Shrew, just to name a few.
