Look at these examples of aller in the Conditionnel Passé:
Je serais allé en Australie si j'avais eu les moyens.
I would have gone to Australia if I could have afforded it.
Tu y serais allée toi-même?
Would you have gone (there) yourself?
Serait-elle déjà partie?
Would she have left already?
Nous serions arrivés plus tôt s'il n'y avait pas eu d'embouteillage.
We would have arrived earlier if there hadn't been a traffic jam.
Seriez-vous partis si je vous l'avais demandé?
Would you have left if I had asked you?
Apparemment, ils seraient partis ce matin.
Apparently, they would have left this morning.
Selon Tom, elles seraient rentrées chez elles vers 3 heures.
According to Tom, they would have come home around 3.
Notice that être is used - not avoir.
Just as with the Passé Composé, some verbs (mostly movement verbs) conjugate with être in the Conditionnel Passé:
je serais, tu serais, il serait, nous serions, vous seriez, ils seraient (Conditionnel) + allé (or other past participle)
Note also that the past participle allé changes if the person doing the action is feminine (allée) or masculine, and singular or plural (allés/allées).

Hi. I am confused about some of the sentences in this lesson
Some sentences seem very similar to "will have" (futur antérrior) and I can't tell the difference. For example: Apparemment, ils seraient partis ce matin. Apparently, they would have left this morning. Selon Tom, elles seraient rentrées chez elles vers 3 heures. According to Tom, they would have come home around 3. Why would you not say"According to Tom, they will have come home around 3" or "Apparently they will have left this morning"?

If we write "Will have, etc." there is no condition to be met, there is a sense of certainty.
Perhaps there appears to be similarity but the point to bear in mind is the mood implied --
certainty or conditional.
Hope that helps.
