This paper examines the implications of post-space to the identity construction of the main characters, Ravi and Laura in the work of Sri Lankan Australian writer, Michelle De Kretser's The Questions of Travel. It investigates the journeys of the characters in Sydney, the meeting point or the post space of Ravi and Laura in which they have to negotiate themselves to the already-existed system. De Kretser's The Questions of Travel, apparently positions the two characters as the representatives of opposing poles, East and West. It can be found out that Ravi and Laura in the end lead the principle of colonial space. Ravi fails to appropriate himself to the Australian environment, while Laura reinforces her status as a white Australian by consistently leading a colonial path.
