There are always risks involved in making decisions, that's why we have to be very careful on what we decide on and the basis for our decisions. Migrating to Australia still possess a bigger gain than negatives
. Sure, we will not be able to do what we normally do here in the Philippines but with perseverance and hardwork we will topple that over. Australia's economy is among the worlds best and they have natural resources to support that. They on a down turn now because of the world crisis brought about by China's starving economy but like any economy, it will bounce back slowly but surely. If you want to consider timing then that could also be a good option but consider the constant upgrades of imigration policies, prices and the rising numbers in migrants. Too soon maybe better than too late (2017 - 2020).
If you've been to the worst then you need not fear that you cannot get through this, Filipinos are born and bred fighters - we thrive on the harshes conditions. The best we can give ourselves is the chance to become better and be on a better plattform. If you have goals of a better life then stick to it, if you cannot obtain it here then don't change it but rather change your plans.
Migrate, why not? but come prepared both financially, physically and emotionally - read about moving into Australia, ask your relatives or friends living in Australia if it's a good idea then plan eveything from assessment, taking the IELTS and the whole VISA application because it takes more than personal will to do all of these. You will have to really decide and put your heart and mind into it.
More importantly, we should focus on what is our main purpose for migrating. Personally, I intend to migrate for my children's future, Education being my top consideration. I believe Australia can also offer far more better living environment, culture, perpective and general life comfort than the Philippines (Traffic, corruption, flooding, crime rate, rising cost of living, pollution, job availabiltiy, education, lifestyle etc).
