Travellers often experience problems in accessing funds in Cuba. Australian dollars cannot be exchanged in Cuba and many debit cards are not accepted. Cash advances may be obtained at banks, large hotels or Cadeca exchange houses against Visa or Mastercard only. Credit cards, debit cards and travellers’ cheques are not accepted if issued by US banks (this includes all American express cards) or Australian banks affiliated with US banks.
