Taught at LaSalle Study Centre, Changjiao; Tutored students at Saint Joseph's Institution International Primary School (Singapore)
Australian who lived in Singapore for most of my life came to HK three years ago.
English can be inconsistent due to its roots and can get complicated. However, one can get by with minimal use of complex structures. I believe that after building a foundation, experience is the most interesting and natural way to learn a language, be it a conversation, reading, writing, or something else.
Everyone has their own experiences and inclinations with learning, but it should be possible to reach practical fluency from scratch within two years of lessons once a week for most, even with little effort (I say this as it is the standard of most high school programs; it is possible to achieve the same within months if one is very motivated).
Hong Kong has many bilingual resources available, from street signs to most government publications - use these as a practice material in daily life, and have a bilingual dictionary to refer to for longer passages. Bilingual books are available and useful once one has reached a basic proficiency. After one is comfortable one might switch to purely English material with a dictionary on hand.
It depends on experience and effort, but the use of an alphabet and the robustness of basic grammar make it easier to build a foundation. Advanced grammar and vocabulary can appear inconsistent or complicated, but build fairly directly upon simpler concepts.
