Help Process to get my child back Colombia

I arrive to Australia since 14 months for studying English and the next 15 on April of 2019, I will back to Colombia for helping to my son, he is 5 years and is suffer a lot psychological damage.

I have been married since 12 years and both (my husband and me) were agree about with this trip to Australia for improving our professional skills with the main goal of achieve a better future for our family in Colombia.

However, I had to acquire a debt in my country considerable and unfortunately, I knew recently that my husband had an extra-relations with another woman and he has another son (he is 11 months). For this reason, I has cancelled my studies in Brisbane and will back to Colombia for soliciting the custody of my son and doing my divorce process. However, I need paying my debt.

Really, is not easier solicit help but I don't have enough resource for starting a new life with my son in Colombia and he is the most important in my life. So, I appreciate a lot the comprehension and any collaboration because in Colombia there are not real support.
