Can I get a visa for a girl from the Philippines if we have not met in person?

My income is that of an aged pension and I have been communicating with a Filipino pinay for over 3 years and will visit her in July and December of this 2017. During our communication, I have regularly been seeing to some minimum comforts for her and her 12yo old daughter and we have both kept all money receipts transfers from Western Union. That all being said, would my age pension restrict me in applying for a visa, for her to come here to Australia, in due course?

Hi Jeff My bother has been internet dating a girl in the Philippines ( apparently )… he talks to her using skype and messenger etc… he's been doing this for around 2 months now… he's never met her or been over there either . he's been transferring money to her just about every week for all sorts of items . like she needs money for medication , her sick relatives , food etc etc… he's even given her money for a visa and plane ticket to australia . and of course she never arrived ( funny that ) as her brother died just as she was arriving at the airport . she also said she got stopped at airport by immigration as she didn't have enough paperwork and only had a one way ticket . i,m absolutely sure this is a scam and he's being cat fished . but even after the airport fiasco , he still believes she's coming to Australia . Do you think this is scam and is there any way she could get a visa to come to Australia .
